Taking the demolition of a large sewage tank as an example, the design of blasting parameters, unit-area load, a reference-area for load and the principle of selecting total reference-area, the calculation of total load, charge structure, priming network and others are discussed.

以拆除一大型污水处理池为例，讨论了爆破参数的设计、单位面积装药量的确定、选取装药基准面和确定装药基准面总面积的原则、总装药量的计算，以及装药结构和起爆网路等；并简述了这种方法的爆破机理。

The head and trail axis speed-time curves of LEFP, speed grads of every liner curvature particulate and section forms under these two different blast ways are compared. The penetration power under different blast ways is simulated with a five-time charge caliber.

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。

The split between the two groups can hardly be papered over.
