查询词典 cathode

After many experiments with aluminium foil of various thicknesses he was able to publish, in 1894, his great discovery that the plate of quartz that had, until then, been used to close the discharge tube, could be replaced by a thin plate of aluminium foil just thick enough to maintain the vacuum inside the tube, but yet thin enough to allow the cathode rays to pass out.

1888年莱纳德在海德堡大学昆克手下工作，他完成了他关于阴极射线的第一项研究成果，他研究了当时赫兹关于阴极射线有与紫外线相似特性的观点，并设计了一个实验，以探究阴极射线是否像紫外线一样，能够通过放电管壁上的石英窗，他获得的结果是阴极射线没有这样的特性。

The invention relates to a method for treating gaseous VOCs by a solid extraction-electro-catalytic oxidation method and a device thereof. The method has the steps that: firstly, an electromagnetic type air compressor is used for controlling the gas flowing velocity by a glass rotameter so as to ensure contaminations in the contamination solution in a gas washing bottle to be stripped into an electrochemical reactor; secondly, microporous aeration heads are distributed in the electrochemical reactor, after being stripped into the electrochemical reactor, the gas is distributed in the electrochemical reactor by the microporous aeration heads, takes parts in the electrochemical reaction and passes through the cathode of absorptive and conductive porous material and the anode of iron sheet in sequence; thirdly, the treated gas finally flows out from the top end of the electrochemical reactor and enters into the gas absorption solution.
