烟火药中 Mg 粉的辐射效应研究

Study of Radiation for Mg in Mixtures of Pyrotechnics

目的研究Ｍｇ粉对烟火药辐射效应的影响．方法在试样中按比例逐渐增加Ｍｇ粉的含量，测定各个试样可见光和红外辐射的输出强度．结果可见光和红外辐射的输出强度增加，但增加幅度在Ｍｇ粉含量的高百分比和低百分比区域是有差异的．结论Ｍｇ粉含量高有利于可见光辐射，Ｍｇ粉含量低有利于红外辐射．

Aim\ To study the influence of content of Mg in pyrotechnics upon the radiation Methods\ The content of Mg in the samples was increased in proportion The intensity of visible and near infrared radiation was determined Results\ The amount of energy radiated in the visible and near infrared region became grater with increasing of Mg content There was difference in increasing extent for different percentage of Mg Conclusion\ It is useful for visible radiation that Mg content is in high percentage Contrarily it is useful for near infrared radiation
