为了满足氢氘光谱实验教学的需要,我们于1979年研制了氢—氘放电管.由于其中有电极,使用时电极上会出现气体的吸附或脱附,因而光谱中会出现杂质谱线,并且也缩短了放电管的寿命.为了克服这些缺点,我们又研制了无极氢—氘放电管.它具有光谱纯、寿命长、亮度高的优点,是光谱实验中一种很好的光源.兹介绍如下,供参考.一、结构和原理图1是我们制作的氢—氘放电管的示意图.管壁是11号硬质玻璃,电极是用镍片做成.去掉电
In order to meet the needs of hydroquinone spectroscopy experiment teaching, we developed a hydrogen-helium discharge tube in 1979. Due to the presence of an electrode, gas adsorption or desorption occurs on the electrode during use, and impurity lines appear in the spectrum. Also shortened the life of the discharge tube. In order to overcome these shortcomings, we have developed a non-polar hydrogen - helium discharge tube. It has the advantages of pure spectrum, long life, high brightness, is a good source of light in the spectrum experiment. As follows, for reference. I. Structure and principle Figure 1 is a schematic diagram of the hydrogen-helium discharge tube we produced. The wall is hard glass No. 11 and the electrode is made of nickel.
