采用CAE(Chemical Eguilibrium and Application)软件对造雾剂的燃烧产物组成和燃烧反应热力学参数进行了理论计算，使用红外测温仪、高速摄影仪和X射线衍射仪等对不同镁粉含量的造雾剂的燃温、燃速和燃烧残渣率进行了分析测试，将二者进行了对比分析，研究了镁粉对于造雾剂燃烧反应过程以及成雾可见光遮蔽性能的影响。理论计算结果表明，平衡态燃烧产物中气相产物主要包括气化的氯化物和CO2、CO、H2O、H2等，凝聚相产物主要为MgO。实验结果表明，镁粉对燃温、燃速的控制作用较大，对燃烧反应和凝结核的生成和核化过程有重要影响。镁粉含量增加到8%时，造雾剂的燃速迅速上升到1.26 mm·s-1，燃温迅速升高到2000 K。当燃温达到1773 K以后，氯化物的核化过程顺利进行，成雾的可见光遮蔽性能逐渐变好。实验结果与理论结果在燃温的变化趋势以及燃烧产物组成方面较为符合，但理论值比实测燃温要高300~500 K，而燃烧残渣与理论计算的凝聚相产物含量方面有所差异，镁粉含量小于5%时，实测残渣率远大于凝聚相产物的理论值，而当镁粉含量大于6%之后，实测残渣率小于凝聚相产物的理论值
