However,it is the dissipa-tive mechanism,i.e.the mechanism of energy localization that attracts one′sattention for the problem of shock initiation.Since the test result of shock initia-tion about fine-grain explosive charge does not support hot spot ignition model,the author of this dissertation advances that the mechanism of energy localiza-tion is coincident with phonon-fracton crossover of fractal network for ultra-fine-grained charge and,moreover,analyzes the relation between shock sensi-tivity and porosity,which is consistent with shock Hugoniot curve for porousmaterials.

由于超细颗粒压装炸药的冲击起爆实验不支持热点点火模型，为此、本文提出对于单晶颗粒半径为微米以下量级的药床，冲击起爆的能量局域化机制与分形网络中弱局域化声子向强局域化分形子的渡越对应，并且根据这一机制分析了超细颗粒药床的冲击感度和孔隙度的关系，结果与多孔物质冲击压缩的P-V图吻合。
