些微地减少阴极电压应该改良这。

Reduce the cathode voltage slightly which should improve this.

减少阴极电压降；

To decrease cathode voltage;

结果表明，随着工件阴极电压、源极电压和气压的增加，等离子体密度增大。

It is shown that the plasma density increases with increasing workpiece voltage, source voltage and gas pressure.

So, when the voltage difference between the plates is zero, or when we just don't have the plates there at all, the cathode rays are not bent, they just go right in a straight line, and they can be detected on this screen.

拐弯来测试它们是否带电,当两板之间电压为零，或者根本就,没有这两个板时，阴极射线是一条直线,它可以在屏幕上。

And what we did was he put two detection plates on either side of these cathode rays, and when he put a voltage difference between these two plates, he wanted to see if he could actually bend the rays and test if they're actually charged or not.

但没有实验证明这件事,这就是Thomson所做的，它在阴极射线旁边放两块探测板,他想通过看当他,在两板之间加上电压后,阴极射线是不是会。
