| 摘 要： | 根据光的电磁理论及光的波粒二象性，从激光对材料的热作用出发，运用“热点”学说，分析了小粒度情况下的吸收增强、弛豫加快、米氏散射及均匀吸收等效应对含能材料激光感度的影响作用，进而得出激光感度随粒度减小而增加的结论。理论分析与实验结果一致。

| Abstract: | Electromagnetic theory, wave-particle duality
of light and hot spot theory are applied to study the effects of particle size upon the
laser sensitivity. The effects of increase in absorption, relaxation acceleration, Mie
scattering as well as uniform absorption on laser sensitivity are analyzed in the paper.
The conclusion is arrived at that energetic materials with the smaller particle size have
the higher laser sensitivity. The results of theoretical analysis are in accord with that
of experiments. |
