大部分的Arduino控制板已经有一个附加到13脚的LED了.也就是说,如果你没有额外的LED硬件,你也可以看到控制板上自带的LED灯闪.
Most Arduino boards already have an LED attached to pin 13 on the board itself. If you run this example with no hardware attached, you should see that LED blink.
针对不均匀电场(棒-板间隙)中绝缘板上残余电荷对50%冲击闪络电压u _(50)的影响做了一些试验研究。
The effect of charges remaining on a dielectric plate upon the 50% impulse surface flashover voltage U_ (50) in the non-uniform field (rod-plane gap) is investigated.
