This paper measured the constitutive relation of soil in the condition of the low stain-rate by Split Hopkinson Press Bar technology. It offers the reference for study in high stain-rate in the future. And simulated the explosion between soil and concrete by finite element dynamic analysis software LS-DYNA3D. Finished the numerical simulation for power of exploding between soil and concrete in different position of detonator and different scale model. Set out the curves of displacement, velocity, acceleration and pressure of different position. Obtained the destructibility of concrete target in different explosion condition. It offers data reference for theory studying and engineering designing.

摘 要：以聚乙烯醇和NiFe2O4/Ni型金属陶瓷压坯为对象，采用热重分析研究PVA在N2气氛中的热脱脂行为，建立PVA热脱脂速率的数学模型，在此基础上，模拟并计算PVA分解产物气体在多孔粉末压坯内的压力构建情况；结合粉末压坯脱脂强度测试结果，分析粉末压坯在脱脂过程中压坯尺寸、粘结剂含量等因素对升温速率和脱脂时间的影响，获得不同半径尺寸压坯的极限升温速率。

Using these diagrams, thermodynamic analysis is carried out to show the effect of technical conditions on soda decomposition of scheelite. It appears that the concentration of has direct effect on soda decomposition of scheelite. When the alkalinity is low, will hydrolyze to , accordingly the decomposition rate of scheelite becomes lower because of the decrease of . So in order to get higher leaching rate in industry practice, it is necessary to use enough amount of soda to serve as digestion reagent and, certain amount of NaOH to maintain high enough alkalinity.

利用这些热力学平衡图对Na2CO3分解白钨矿的工艺条件进行了分析，认为溶液中浓度直接影响白钨矿分解，而当碱度较低时，Na2CO3将水解生成，从而降低浓度，进而降低白钨矿的分解率；故在工业实践中，为使钨最大限度地转入溶液，除了保证足够的Na2CO3用量，还必需添加NaOH以维持一定碱度。
