Aunt Zhang was very young. I was very sorry. I was late. Some of the most needed things have been bought after July 7th, and it is found that there is another such app that can be shared with friends and discuss various new and wonderful things. Since then, let’s talk about a 30-year-old toy. The first thing I want to say is the first notebook of my life in thirty years. Dell travels. At first, I thought I would be able to play games with my leisure time, plus I had an old Dell laptop in my family, so I didn't worry about choosing Dell 7567-1745. After the notebook was bought, it took a long time to toss. From the beginning, the sellers were allowed to add memory to their own hands and change the screen. For the solid state, a total of 9K oceans were tossed before and after. After the actual purchase, I discovered that I had already lost my mind to the game. On average, I could turn on my computer for less than half an hour a day. Looking at the instinct of the game instinct to race horses, it really regrets that it was better to choose XPS15. Now the role of the computer is nothing more than to play cool songs, take a look at local forums, there are some lossless songs and some kind of mobile phone can not push the kindle e-books. I do not like to be bound by a variety of wire, so support for Bluetooth is preferred, the speaker is selected bose soundlinkmini2 black gold version, the same is not tangled with other brands of other models, for this speaker, it can be said that the grass has been a long time. Prior to this was the millet-generation cannon, 89 Bluetooth speakers, ipad, and mobile phones. I was a wooden ear and I had always felt that the sound quality of 89 speakers was also good until Bose opened it. There is no doubt that the small steel cannon entered the trash bin that afternoon. The ears of wood can feel the difference between the two at the first time. Of course, the price gap is also huge. A tiny bluetooth speaker, with an unexpectedly heavy weight in her hands, can connect two devices, which just allows me to switch between my computer and my mobile phone. A full charge allows me to use it moderately for a week. The second, standing on the street to enjoy the quiet of the world, sony mdr-1000x Bluetooth noise reduction headphones. Noise-reducing headphones used to be a bose QC 35, but also went to audition, deeply shocked by the feeling of a completely different world after wearing headphones, eyes close to you and I close, eyes closed but far apart . Go home directly to the computer and go straight to Taobao. It is also a coincidence that the result is ready to buy, Taobao sent a push, write is the comparison of qc35 and 1000x. Both are at the same price as the 2800+ (Tmall flagship store). As soon as an article goes down, the sony mdr-1000x is blinded. Fortunately, it seems that my choice is right now. In no way inferior to the qc35 noise reduction, rejection qc35 a street sound quality, not to mention the quick reminder mode covering the right ear of bills of lading, etc., but have to mention, slightly lower than the qc35 wearing comfort - can only say It's a little short. After all, when I used it most, it was the nap time. After two hours, I didn't feel any discomfort. I think a good noise-cancelling headset is indeed an essential part of improving the quality of life. It can bring me peace and tranquility when it is most needed for a moment. The third is also the Dafa a35 player. The motivation for entering the player is purely to stay away from the mobile phone. One simple idea is that you can listen to the song without a mobile phone. Due to work reasons, there are endlessly busy things in the daytime. It is also a very pleasant thing to put down your mobile phone to enjoy music and read novels. Selecting Dafa naturally comes from having a Dafa headset on hand. It is said that there is a mysterious increase between the two. Both parameters support LDAC, but unfortunately it is a 192k and no ears that can't be heard without damage. Such technologies are undoubtedly for me belong to the category of brain release. After all, it was chosen because of Bluetooth + good looks + Dafa beliefs. The fourth is because summer is too hot to wear a headset, so I just bought an i60 from Amazon, the same life for the first time alone to buy headphones (usually bought Walkman to buy a mobile phone, anyway, never In the case of a bad one, the first ear that comes with the arrival of the goods is really a feeling of being on the wrong ship. The sense of hearing is that all the voices are lumpy and disappointed. According to Great God, the performance of this headset will greatly change after it has passed, but I did not give it this opportunity. Free fish out of the transfer to Baia bta (open box see the other original). Self-students began to love nothing more than listening to music (really listening and not singing) + reading novels. From the junior high school era, you can use the brand name you bought in half a semester to hear later MP3s to music phones, to the current audio equipment, or to rent a physical novel from a student's school desk to a mobile phone screen. Today's e-paper books, each time the equipment is updated from the initial surprise to later into the plain of life, the original intention of buying them is the same. Whether I can use them or I want to use them - it is worth buying. There was so much trouble. Do not want to write, then it is over. Semiconductor Fuse and Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.

The last thing to say is the same: kindle. I was outdated and only used it for the first time last month. A word can be described as: hating late. Of course, I used it to look at online fiction (yes, that's why I didn't force it)—an ingrained hobby from the student days. The benefits of the electronic ink screen have always been for the hearsay. It's no difference between the eye and the paper. I'm scoffing at it. It wasn’t until I saw the real thing—I had gone and it was really! Now it's really the most frequently used electronic product that I have on hand. After buying it at least, you can throw all the original piles of novels into the trash can, up to 300MB can get things done, why spend a big box to waste limited space.
