Because in industry expandable graphite is mostly used as seal material and extensively applied in high-tech domains, such as nuclear power plant, avigation and petroleum industry, then often erodes the metal material which connected with it and loses seal , so the sulfur content of the expandable graphite is an important target to achieve , at the same time the industry manufacture need the greater volume .

因为可膨胀石墨在工业上主要被用作密封材料被广泛用在核电站、航空、石油工业等高科技领域，这样，其作为高级密封材料时，常腐蚀与其接触的金属材料，造成密封失效。所以含硫量是一项很重要的指标，同时较大的膨胀体积也是工业生产所需要的。

In this paper, the dynamic compressing experiments for the matrix material of the tungsten alloys which have been three different deforming(0%、 32.6%、 44.6%) processed have been performed by the experimental technology of separated Hopkinson pressure bar and many accurate datum have been obtained. Also the three materials have been compared with each other and analyzed. The results show that the optimized values are in a certain range to optimize the materials by changing their deforming technology. The parameters of constitutive model of Johnson-Cook have been fitted based on the datum. Then proceed to the next step, adiabatic shear band of these three matrix materials has been analyzed with finite element method. The result shows that the relations between stress and strain are different because of the differences of technical process of the three materials, but they are in great commonness in the material experiment and in great coherence in the distribution of time and space, which can been seen from the space distributing figures of plastic strain.

It is also discussed that the Ag powder was added into the electrode by utilizing the decomposition of AgNO_3, but the result is not so good. Scanning by SEM, the active material is broken with long time mixture or temperature is insufficient to decompose completely. The mixed conductive additive was put into the active material LiFePO_4 to improve the conductivity.

本论文还试探性的利用AgNO_3的高温分解性在电极中添加Ag粉，但结果却不令人满意，通过对机械球磨后的电池材料进行SEM扫描分析，发现电池容量衰减的原因是长时间的机械球磨使得活性物质的晶体破裂，还有一点可能是因为温度不够高，AgNO_3分解的不彻底，使得电池中还存在着AgNO_3，影响了电池的性能。
