The first time I contacted an Apple product was just a freshman. At that time, it was 2005. At that time, there was no iPhone, only a music player, and I liked music and I became ignorant. Later, Apple introduced the mobile phone. I didn't have the time to buy it first (after describing the reasons in detail), but ended in the classic generation of Steve Jobs. Because of personal needs, I chose the top version, non-low-grade version, and top. The version is also commonly known as the emperor's version. Everyone often says that Aunt Zhang has three treasures. I chose Apple to have three treasures. I will introduce the “three treasures†I chose for myself: iPod, iPhone, iPad. When I remember in college, a tutor of a programming class told me: A piece of software, if familiar with it is divided into two concepts, one is familiar with how to write it, the other is familiar with how to use it product I can not create Come out, then I'll be a familiar user, how to choose, how to use, according to the needs of my routine to choose to use, let me become the lamb of the trendy digital products industry, and finally I became a digital product Familiar with the user
iPod Music Player:
The loss of the iPod series is Apple’s decision-making decision. In September 2014, Apple officially announced the suspension of production of the iPod. The iPod series I first contacted was the iPod shuffle 1 generation. At that time, I bought 512 MB. Although the Meizu and Onda (the subtle relationship between Meizu and Onda) was hot, the new force was the main force and the "Feixin" +1 7th battery can be played. N hours, but it can't shake me to see the iPod shuffle shaken at the counter. At that time, Apple had no direct-operated store in China (Apple's first direct-operated store in China was at 10:00 am on July 19, 2008 in Beijing. The opening of Sanlitun is only a small counter for Apple products. At that time, Apple's popularity in the country was relatively sluggish. Except for music enthusiasts who would understand Apple's brand, others would only ask Apple what it was and only knew Meizu and Onda (just like Speaking of the first reaction of domestic mobile phones, Xiaomi and Huawei are the same.) When he and his friends mentioned Apple, he also highly recommended Meizu and Onda players. However, Meizu was transformed from a music player into a mobile phone company. Onda became a computer accessories company. Also involving the mobile phone industry as a benchmark in the mobile phone industry
At that time iPod shuffle transmission of songs is also very troublesome, you need to install iTunes to import songs, and import songs must be converted to m4a format, and later found that you can use Foobar2000 and iPod ToolKits do not need to use iTunes to import songs
(The above four figures are borrowed, not taken by me, because my box has been lost and is missing just to show the packaging of this product)
When the iPod shuffle 1 generation 512MB, can hold more than 120 high-quality songs, when the Apple packaging is green, then really think that packaging more "local" time seems to have spent only a thousand dollars less than Buy, the price is not expensive (relative to Meizu at that time), silicone protective sleeve actually sold 100 yuan a set, when the protective sleeve can only buy Apple authorized third-party products, Huaqiang Shenzhen has not found the gadget's profit at that time objectivity
Here is my iPod shuffle physical photo:
Plug in your computer to use the latest version of iTunes or import songs into iPod shuffle. Apple's products are almost at the forefront of the industry and feel innovative from the design of the United States. Early playback devices were mostly based on memory cards. At that time, the price of memory cards was very high, and prices for 8MB, 16MB, and 32GMB were all high. 3,4 hundred yuan Apple launched a large-capacity hard disk music player makes music enthusiasts crazy and fascinated, crazy is relatively large compared to other memory card capacity N times, fascinated that I can carry my music library to go out. In the later period, Apple returned to the flash player from the hard disk player. Because the good technology of the flash memory card is greatly improved, the price is also reduced. The flash memory has more excellent anti-vibration and anti-magnetic ability than the hard disk, and brings about the miniaturization of the volume. The player's volume is reduced in height for portability.
Nearly every generation of innovations in the Apple Music Player family can be set as industry benchmarks: large-capacity hard drives, key discs, long-lasting endurance playback capabilities, white designs, and color displays. Meizu learn from Apple's successful masterpiece: Meizu M3, Meizu mini player and so on. The success of Apple's music player also came to an end. When the iPod was sold in September 2014, the number of iPod players sold globally could not be considered. When you watch the US blockbuster, you often have an Apple player in the mirror, so you can think of Know the iPod's popularity in American homes.
iPods often feel like music enthusiasts: boiled water, less rendering, strong thrust, the effect of highlighting the installation of the amp! Because of this, there are a lot of enthusiasts secondary DIY improvement adapters and so on. Although the iPod shuffle I bought didn't have too much bulging effect, the small size of the device was like the green arrow chewing gum, which made it very convenient to carry out. Now it has been used by my old things and it became the music I carried while jogging. The player had bought iPod shuffle for a month without quality problems like many USB flash drives. After inserting the computer, there was write protection. The file could not be written, but only the first time after the sale. Understand that digital products are mainly based on repairs. The first time I heard that I could directly change machines, I was still a little excited at the time.
iPod shuffle use experience: lightweight and compact convenient pocket to carry, high endurance, good sound quality without fever, although there is no screen, but it does not hinder the use, listen to the songs are their own selection back, not to collect more songs in the warehouse For the purpose, it took 11 years, and now it is still in normal use. There was no problem after the replacement of the new machine. Now, people who don't understand think that it is an Apple U disk, because the shape is too U disk. .
iPad Tablet:
The iPad I purchased was the iPad Air 2 128G (WLAN + Cellular Edition). The main reason I did not purchase the iPad in the early days was that I was not satisfied with its screen graininess and no camera. Later I upgraded to the retina+camera+fingerprint and met my personal needs: Retina (high resolution), camera (8 million cameras), fingerprints (security), experienced many generations to purchase iPad Air 2
Here are my physical photos of my iPad Air 2:
The revolutionary iPad Air 2: equipped with A8X triple-core processor, memory upgrade to 2GB (2GB memory is also one of the many factors that shake me to buy it), usually work needs to use the design, so sometimes I will design on the tablet again Go to computer, computer to tablet, jump back and forth. The software used has a large memory footprint, so the primary consideration is the start of 2GB. The original iPad Air 1 was only 1GB. Running a software often results in slow operation and low efficiency. We often go out. If we don't have a network in the information era, The communication between the work and the partners is very troublesome. Sometimes it may be the loss of millions of small businesses. The time is money, so I bought the Cellular version and can use the data flow through the card. The Cellular version has a more practical function. More GPS module, sometimes I have a short holiday break in half a year, go out to travel, carry a tablet computer is also convenient for me to locate, although there are mobile phones, but many of the same features are still good
Now the iPad series came out: iPad Pro, performance has been replaced, but unfortunately there is not much breakthrough in performance that does not attract me, so there is no start, I usually start with digital products, are first from the performance and for my own use is If it is useful to buy, if there is not much demand for me, I will not consider this generation of products, and may wait for the emergence of the next generation of replacement products, and find points of interest to buy.
iPad Air 2 use of experience: the first tablet for work to buy the tablet, all aspects of a bit more prominent, brought me the convenience of the work. 128G is my preferred capacity, work and entertainment capacity segmentation points, most of my entertainment after work is a photo and music, although the iPad camera performance and mobile phone camera or other professional camera photo there is a big gap, but the iPad's camera function I also use it as an auxiliary camera for my use, post-processing photo video clips using the iPad's large screen is very convenient, especially when I started GoPro HERO4 Black after recording video clips used very convenient, reflected in the timeline zoom accurate clip. Everyone knows that GoPro HERO4 Black has no screen, and the screens purchased separately are also in general. Using a mobile phone to connect when the viewing screen is sometimes inconvenient, so iPad is often used as a GoPro HERO4 Black viewing screen.
My GoPro HERO4 Black sun list:
iPhone4S mobile phone:
iPhone, I bought for myself is the iPhone4S and iPhone6S Plus iPhone4S bought the 64G Emperor Edition, why 4S before buying it? Mainly the upgraded features of iPhone4S in all aspects attracted me, especially the upgrade on the camera, brought me a lot of convenience, I like to take pictures (I went to shoot, not to be shot), prompting me Most of the reasons for playing with a lot of mobile phones: I chose to take photos of it and buy it. You can look at my previous mobile phone articles, I basically rewrite the performance of cell phone shooting
The following is my iPhone4S physical photo:
I have measured mobile phone articles :
Nubia Z9max Elite Edition:
Glory V8:
Huawei Maiman 5:
The above three articles are articles of my mobile phone. Each article is the quality of the article and the sublimation of the pictures to the present. At the time of publication of each test article, I will review my previous writing reviews. And look at the evaluation of others, absorb the essence of others to improve their weaknesses, hoping to show that they feel more perfect all aspects of the test article for everyone. Every time I test new products, they are self-restrained and strive to break the same type of articles I wrote last time. I think that the articles are homogenous with others. If there is a chance, I hope everyone will look forward to my next mobile evaluation. Bringing different pictures and texts to test articles Duang~ I am more refusing to appear in the ZLJJ live appearance, maybe there is a surprise
Returning to the theme, the iPhone4S was the first iPhone product launched by Tim Cook on October 5th, 2011, and was also called "iPhone for Steve", commemorating the legacy of Steve Jobs and Steve Jobs. iPhone4 and iPhone4S contrast, although the appearance is not much difference, the leap in performance is not just a little bit different, the CPU from single-core A4 to dual-core A5 provides better multitasking performance and graphics performance, camera 500 million upgrade to 8 million (3 million increase, the effect of the finished product is very different, so iPhone4S shooting performance for a long period of time at the time is the benchmark for the mobile industry camera)
I use iPhone4S to take photos:
The sample of iPhone4S+ later software adjustment is very good, so my phone has a full picture, and sometimes I shoot a short video, so the capacity of 64G basically meets my daily needs.
iPhone4S experience: My iPhone4S has been following Apple's official iOS 9 system upgrade from the native IOS 5, many people say that to upgrade to iOS 9 is the rhythm of death (card dead slow death), after the upgrade is indeed a card, but The card is embodied in running the APP and the system, it is a bit like the old computer running WIN7, memory tight, CPU running tight and other functions can also be, for my focus on the use of camera function, then there is not much impact. Prior to upgrading iOS 9, I also considered not upgrade, but in view of the use of the post-app update APP to upgrade the system, after the upgrade is still acceptable to get the card, iPhone4S satisfactory camera performance has been acting as a long time in addition to the micro-single "Lightly dressed" portable products, probably from 2011 until about 2014, 4 years, iPhone mobile phone is also experienced a lot of generation of shelves and listing, the middle of the performance of the replacement model is not a big leap, for me personal There is no major breakthrough in the required camera performance, iPhone4S to iPhone6 ​​camera has been 8 million pixels, so I have not been considered to replace the iPhone4S, wait until 2015, iPhone6S Plus released the camera to upgrade to 12 million pixels, only once again shaken me Change the desire of camera phones
iPhone6S Plus phone:
In 2015, the release of the iPhone6S Plus, the first time to buy the 128G Emperor Edition 128G is mainly due to consider the previous use habits and needs, plus iPhone6S Plus support 4K video, recorded video takes up very large space, before also explained why to buy For iPad Air 2 128G, GoPro HERO4 Black was also purchased, so 128G is the only option I have to purchase. I use a mobile phone to edit my video without using iPad. IPhone6S Plus 12 million camera shoot photo imaging for me personally can replace the general card machine, the color of the eye-catching eye-catching aesthetic like, especially with APP:Camera+ or ProCam shooting can get TIFF to format Non-destructive photos, take up a lot of space, non-destructive photos is also a format I often use after shooting iPhone6S Plus
The following is my iPhone6S Plus physical photo:
I use iPhone6S Plus to take photos:
iPhone6S Plus's optical image stabilization lens imaging is very good. Compared with other mobile phones, the photos taken are warmer, and the camera's camera performance is growing stronger. Some people disdain the mobile phone for taking photos (such as certain equipment parties, photography enthusiasts, etc.), but themselves Like it, mobile phones can shoot large movies. The pleasure of taking photos is to write the photographer’s ideas at the time.
iPhone6S Plus experience: 6S is not only an upgrade to the hardware on the 6th, the biggest feature is to join the Live Photos feature, a few seconds of dynamic photos to enjoy themselves, but it is a pity that localized transmission Far from being well-distributed by the Internet, if you increase the spread of the Internet later, Live Photos will have more ways to play. If you run a large-scale software or game, it is prone to fever. If you use it for daily calls, you have to charge one day at a time. When I go out for a long time, I need to carry mobile power to supplement the power. The battery life is still relatively long battery life. It's a lot weaker than it is.
iPhone7 highlights: camera
The iPhone7 series has been released, and there is not much change in the appearance of 6S, but the hardware upgrade made my interest the most, especially the iPhone7 Plus dual cameras (pixels stay at 12 million), I have previously used the glory V8 and Huawei P9 Both are dual camera designs. Glory V8 for general consumer groups, Huawei P9 for the camera fashion consumer groups, the difference between the two is a non-certified camera (only JPG lossy format photos can be saved), a Leica-certified camera (you can save JPG and lossless format photos)
My Huawei P9 sun list:
Mobile phone camera function is now the mobile phone "standard", although a few years ago, mobile phone manufacturers have been for a long time for the performance of the photo enlargement and promotion, and later found that consumer groups have been to this kind of performance amplification has reached fatigue after the change to the present When the popularity of the limit border propaganda, forget the essence of the daily use of the most appropriate mobile phone users.
The iPhone 7 Plus seems to use the "dual camera" technology that has been ruined by Android. The actual difference is that the Huawei P9 dual cameras use "color + black and white" imaging (2 cameras are 12 million pixels, F2.2 aperture, 2 The cameras are all working with independent sensors, but they do not support optical image stabilization. Huawei P9 uses this color + black and white imaging technology to enhance the ability to take photos under low light conditions. Xiaomi also couldn't keep releasing Red Rice Pro. Red Rice Pro is Millet's first mobile phone with a dual camera design, but the main camera is 13 million pixels F2.0 aperture (responsible for recording image information color) + auxiliary camera 5 million pixels F2.0 aperture (responsible for recording the depth of field data changes), technology is also Before long HTC M8 played in 2014: first to take a picture after the focus technology, this technology is that now just look at the wine for a new bottle, the real dual camera change is highlighted in the iPhone7 Plus: both lenses are 12 million ( Dual cameras support optical image stabilization, support 2x optical zoom, wide-angle lens F1.8 + telephoto lens F2.8 combination, light field imaging technology)
The function of taking photos after focusing on the Glory V8 and Huawei P9 is not good. You can see the figure below (Glory V8 shooting):
Later use of focus, like the late PS, seems very rigid and rigid in the photo, there is no traditional effect of depth of field effect. Sometimes the desired focus is not precise and it is very distressing
The official sample of iPhone7 Plus:
Not to talk about the careful adjustment of official samples, only from the technical point of view, we can see that the depth of field obtained after the first photo after focusing is very smooth, so iPhone7 Plus has also been called by many media: is a major revolution in the history of mobile photography, The second generation supports the "camera first focusing function" dual camera from the hardware level. Optical zoom is also a good use of features, we must know that mobile photography is almost all digital zoom, camera using optical zoom camera is very few, many are short-lived, there is no follow-up upgrade models. The change from the camera alone made me very interested in the iPhone 7 Plus.
Cancel 3.5mm audio interface
3.5mm audio interface with music enthusiasts how much the hard way, iPhone7 cancel the 3.5mm interface makes DIY manual line to improve the silver purity gone, after the change to make Bluetooth headsets more popular, like wireless, then consider the Bluetooth headset, if you want Wired can use Lightning interface headset or Lightning conversion 3.5mm interface, wired and wireless contrast, wireless more popular in the future, but the Bluetooth headset needs to solve 2 problems: battery life and non-headphone volume size, these 2 Are the most urgent issues. The cancellation of the 3.5mm interface has both joy and worries, just as Apple's use of the Lightning interface was mixed, and the last time proved that the Lightning interface was a necessary product of the changing times. Bluetooth headsets and Lightning interface headsets are now emerging as a lot of manufacturers spring up, 2 kinds of headphones, then I will choose Bluetooth headsets, because Bluetooth headsets are more versatile than Lightning interface headsets, you can use to other devices, the limitation of Lightning interface headsets Apple devices only
The appearance of Apple AirPods headset can be foreseen in the future combined with AR, VR technology sublimation to another level of technology
I use Apple's products are all fine and detailed, each one is the era of change, continue to innovate in the transformation, look forward to the iPhone 7 across the times of change
Finally put two GoPro HERO4 Black test shots:
Industrial Energy Storage System
The main function of the Industrial Energy Storage System is to store energy in the industrial field to meet the energy demand in the industrial production process. It is an energy storage solution for improving energy efficiency and power supply stability in industrial production systems.
Main effect:
Energy peak shaving: Industrial energy storage systems can store energy and release energy at the peak of energy demand to meet the high energy consumption demand in the industrial production process. This helps to achieve a balanced deployment of energy and avoid energy waste or power outages caused by imbalances in energy supply and demand.
Reserve power supply: When the power supply of the power grid is unstable or there is a power outage, the industrial energy storage system can be used as a backup power supply to continue to supply the power required by industrial equipment and ensure the continuous operation of industrial production.
Energy saving and emission reduction: Through rational use of energy storage, industrial energy storage systems can optimize energy consumption and reduce energy waste, thereby achieving the goal of energy saving and emission reduction, and reducing the impact of industrial production on the environment.
Differences from other energy storage systems:
Scale and capacity: Industrial energy storage systems usually have large scale and energy storage capacity to meet the high energy demand in industrial production. Home energy storage systems, on the other hand, are usually smaller and are mainly used in home photovoltaic power generation systems.
Application scenarios: Industrial energy storage systems are mainly used in the industrial field to meet the energy demand in the industrial production process. The Home Energy Storage System is used in the home photovoltaic power generation system to improve the energy self-sufficiency of the home.
Control and management: Due to the large scale of industrial energy storage systems, their control and management require more complex and precise technical means to achieve efficient energy utilization and stable supply. Home energy storage systems are usually relatively simple and easier to automate and manage.
Generally speaking, the main function of industrial energy storage systems is to meet the energy demand in the process of industrial production, realize the balanced deployment of energy, and the stability of the power supply. Compared with home energy storage systems, it is different in terms of scale, capacity, application scenarios, and technical complexity. The application of industrial energy storage systems helps to improve the energy utilization efficiency of industrial production, optimize energy management, and promote sustainable development and green production.
