平行板电容器两板间距为d,电源电压为6V．闭合S后将板间距离减为d／4,再断开S,又将两板间距离恢复到d,此时电容器两极间电压为_____V．附带问一下,题目里没说明正负极,但是接地的一般是负极,我会做了，只要跟我说一下，题目里没说明正负极，但是接地的一般是负极，

It was months ago that they confirmed the retro release of the “Grape” Nike Air Max 95. Now the race to grab your own pair can start, as 21 Mercer has received their shipment & has them on the market now.
Like so plenty of classic colorways of the 95 that we’ve seen this year, this look is true to OG. The white midsole works with the gradient upper, which transitions in to a black midfoot, complete with black 3M. Teal lace hoops work with the purple tongue & Swoosh, as well as the teal Max Air bags below, to break up the simple greyscale upper. Check together with your local retailer if you’re after a pair,cheap nike shox, as they’re hitting select Nike retailers soon.

24V,牢记一点,s断开,电荷量不变,s闭合,电压不变.接地通常默认为负极
我已经说了啊,对的
