火花中光谱激发过程的瞬时观测

对火花光源中谱线激发强度的时间过程进行了测量;所用装置的分辨时尚为1×10^-7秒。在放电时间约为2×10^-6秒,工作于临界阻尼状态下的火花中,激发电位高的离子线先出现,而且很短暂。用实验证明在3961.5?重迭的两条AlⅠ与MoⅡ谱线在时间上几乎完全可以分开,提供迴避干扰而利用这些灵敏线作光谱分析的可能性。

INSTANTANEOUS OBSERVATION OF THE SPECTRAL EXCITATION PROCESSES IN THE SPARK

The time resolution process of excitation intensity of spectral lines in the spark light source is measured. In the spark, operating under the critical damping state, with flash time at about 2×10^-6 Sec., the ion lines of higher excitation potential first appear and appear shortly. Experiments show that, as to time, two lines, All and MoⅡ, piled up at 3961.5?, may be fully seperated, providing the possibility to avoid the interferences and to use the sensitive line as spectrum analysis.
