为了研究Mg/Sr(NO3)2和Mg/Ba(NO3)2药剂的燃烧光谱分布, 利用全波段辐射计分别对Mg/Sr(NO3)2和Mg/Ba(NO3)2药剂的燃烧光谱进行测试, 得到这两种烟火药剂的燃烧光谱分布图。通过对燃烧光谱的研究, 在Mg/Sr(NO3)2药剂燃烧光谱中, 620~760 nm的辐射强度在总能量占80.59%；而在Mg/Ba(NO3)2药剂的燃烧光谱中, 500~578 nm的辐射强度在总能量占21.15%, 578~592 nm的辐射强度在总能量占3.30%, 620~760 nm的辐射强度在总能量占60.41%。通过燃烧光谱和导数光谱相结合的方式作为鉴定这两种烟火药剂类型的手段。

The burning spectra of Mg/Sr(NO3)2 and Mg/Ba(NO3)2 compositions are tested respectively to obtain the burning spectrum distribution maps with the whole-band radiometer for analyzing the distributions of burning spectrum. It can be concluded that the total radiant energy of 620~760 nm is 80.59% in Mg/Sr(NO3)2 composition burning spectrum through researching burning spectrum. And in Mg/Ba(NO3)2 composition burning spectrum, the total radiant energy of 500~578 nm is 21.15%, 578~592 nm is 3.30% and 620~760 nm is 60.41%. Combining the burning spectrum with the derivative spectrum is served as a means of identifying both types of compositions.
