关于应用脉冲激发光源提高光谱分析的准确度的合理性方面,以前[1,2]已经指出过,并且在借助于活化同位素的情况下,获得了关于原子在这种光源的电极隙间空中分布的初步知识。现在的工作是这些研究的继续,其目的是更系统地研究脉冲电弧的最重要的物理参数,它们可以说明脉冲电弧对测定准确度的影响以及查明应用这种光源比应用普通的直流或交流电弧的准确度高的原因。光源温度测量的准确度已经作了改进,并进行了脉冲光源中电流强度的估计,以及取得了 With respect to the rationality of using pulsed excitation light sources to improve the accuracy of spectral analysis, it has been previously pointed out [1, 2] and with the aid of activated isotopes, an agreement has been reached concerning the spatial distribution of atoms between the electrode gaps of such light sources The initial knowledge. The present work is the continuation of these studies and its purpose is to study more systematically the most important physical parameters of pulsed arcs that illustrate the effect of pulsed arcing on the accuracy of the determination and the application of such a light source over the application of ordinary DC or AC The reason for the high accuracy of the arc. The accuracy of the light source temperature measurement has been improved, and the current intensity in the pulsed light source has been estimated, and the
