为了实现燃烧型抗红外发烟剂配方的快速筛选, 文章在基于最小自由能法的烟火药燃烧产物预测模型的基础上, 设计了燃烧产物推理机, 建立了燃烧型发烟剂光谱特性专家系统, 研究了利用专家系统进行发烟剂配方快速筛选的可行性。 在用户输入发烟剂配方后, 专家系统能够计算出发烟剂的燃烧产物及其含量, 然后利用红外加谱技术, 对各产物红外谱图进行加合, 模拟出烟幕的红外谱图, 进而利用面积积分法, 预测出烟幕在3～5 μm和8～14 μm的遮蔽指数。 文章使用FTIR光谱仪对一种HC型发烟剂进行了测试, 结果表明, 专家系统的计算产物与实际产物相吻合, 遮蔽指数预测值与发烟剂的实际测试表现一致, 为燃烧型发烟剂配方的快速筛选提供了一种新方法。

The present paper studied the application of expert system in prediction of infrared spectral characteristic of combustible anti-infrared smoke agent. The construction of the expert system was founded, based on the theory of minimum free energy and infrared spectral addition. After the direction of smoke agent was input, the expert system could figure out the final combustion products. Then infrared spectrogram of smoke could also be simulated by adding the spectra of all of the combustion products. Meanwhile, the screening index of smoke was provided in the wave bands of 3-5 μm and 8-14 μm. FTIR spectroscope was used to investigate the performance of one kind of HC smoke. The combustion products calculated by the expert system were coincident with the actual data, and the simulant infrared spectrum was also similar to the real one of the smoke. The screening index given by the system was consistent with the known facts. It was showed that a new approach was offered for the fast discrimination of varieties of directions of smoke agent.
