1·A chromium hollow cathode lamp was used as a light source instead of the deuterium continuum source.

铬空心阴极灯可代替氘灯作为测定光源。

2·This assembly uses mode of first absorption then spectroscope , excitation source of deuterium hollow cathode lamp or broadening line hollow cathode lamp.

采用“先吸收后分光”方式，氘空心阴极灯或变宽谱线空心阴极灯作激发光源。
