真空放电

Although Lenard at first followed Hertz in believing that the cathode rays were propagated in the ether, he later abandoned this view as a result of the work of Jean Perrin in 1895, Sir J.J.

赫兹因此建议可以用铝薄板将放电管内的空间一分为二，在空间的一部分内，阴极射线由常规的方法产生，而在空间的另一部分，可以在真空的条件下观察阴极射线。

It is concluded that,at low-pressure operation of magnetron sputtering system and high pumping rate the potential of discharge depends directly on the reactive gas concentration.

本文研究了反应式磁控溅射方法利用Ar/N2混合气体镀制氮化铝薄膜的工艺过程，实验表明在高真空和高泵浦速率条件下，放电电压直接依赖于反应气体珠浓度。
