In modern life, we rely on lithium-ion batteries to power our devices, from cellphone to laptops. These batteries are amazing; they're able to power our devices for several hours with a single charge. But they aren't permanent perfect. If made or used improperly, they can swell over time. Not only is a swollen battery strange looking, it can als...

The best laptop for video editing follows these five principles:(1) Running memory: You can choose 16G or above if you have a sufficient budget, and 8G or above if you have a medium budget. If the running memory is large enough, you can avoid freezes and crashes, and improve the smoothness of preview and export.(2) Hard disk memory: SSD hard dis...

“Laptop battery swelling” is actually what it sounds like: a swollen (read: distended or bloated) laptop battery. And in some cases, a swollen laptop battery can result in a damaged laptop chassis as well: As the bloated battery expands, it can warp the chassis, the touchpad, the keyboard, or even the display, and cause them to bulge out and spl...

一年中总有一些非常干燥的日子，当你穿衣或开门时，你会突然感到好像被什么东西电了一下。这时就是静电在起作用。静电是指材料内部、表面或材料之间电荷的不平衡。电荷会一直保留，直到能够通过电流或放电将其移走。当我们穿着引起摩擦的衣服时，静电的正电荷和负电荷会分离。此时，电子可能从一种材料移动到另一种材料，从而在一种材料上留下多余的正电荷，在另一种材料上留下相等的负电荷。当材料分离时，它们保持这种电荷不平衡。 热和电荷可以引起电荷分离 加热会在某些材料的原子或分子中产生电荷分离。所有热释电材料也是压电材料。此外，带电物体靠近电中性导电物体也会导致中性物体内的电荷分离。这称为静电感应。这意味着如果我们给电池充电，可能会产生静电。 静电可以用来给电池充电吗？ 理论上可以，但给电池充电的是电流。与静电...
