许多实验研究工作中,常需要一个很强的连续紫外光源.例如研究某种物质蒸汽的光致电离;研究物质的紫外吸收光谱;在医学上和化学研究方面,工业分析方面也都有着广泛的应用。我们为了研究紫外区域的吸收光谱,迫切需要这种光源(至于其他的例如热固体对于上述目的是不合适的,因为固体即便在可能得到的最高温度下,所发射的紫外光也比较少).我们知道一个充氢的低压放电管,在3000V左右的电压下,电流为几百个毫安时,能够产生
Many experimental studies often require a very strong source of continuous UV light, such as studying the photoionization of a substance vapor, studying the UV absorption spectrum of the substance, and also having a wide range of industrial and medical analyzes in both medical and chemical research application. In order to study the absorption spectrum in the ultraviolet region, we urgently need such a light source (as for other thermosets, for example, these are not suitable for the above purposes because the solid emits less ultraviolet light even at the highest possible temperature). We know that a hydrogen-filled low-voltage discharge tube, at a voltage of about 3000V, when the current is hundreds of milliamperes, can produce
