In chapter five, we apply this new method to the research the thermo-physical properties of Zirconic metal. By comparing the numerical results with the experimental data, we think that the equations of state considering thermal effect by using the new method are better than old method.

在第五章中将这一新的计算方法应用于对金属锆的研究当中并将理论计算结果和实验数据进行验证、分析和讨论，结果可以发现改进后的方程比以前的好。

Therefore, the melts and coalesces of Al during the combustion process can inhibit diffusion of nitrogen from outside due to collapse of the pores.

由于金属铝的熔点较低660℃，而金属锆的熔点较高1855℃，在燃烧反应的高温下，金属铝要熔融团聚，阻碍氮气向试样内部的渗透。

Meanwhile the novel solid base ,namely CaO-ZrO2[9]solid solution has been reported in recent years, Obviously, the acidic-basic surface and redox properties of zirconia played the significant roles, and the formed solid solution efficiently prevent the active component from lixiviated into the reaction medium.
