混合物质高压状态方程的计算

Calculation of equation of state of a material mixture under high pressure

介绍了在温度相同的条件下,混合物中各组元通过密度-压强迭代法,达到温度和压强平衡,再结合叠加原理,编程计算出混合物质状态方程。为验证该程序,对氘氚与氩按不同比例混合时的状态参量进行了分析。当氘氚中含少量氩时,计算得到的状态方程与纯氘氚符合较好;同样地,氩中含少量氘氚时的状态方程也与纯氩的很接近。这说明该程序是可行的。

At the same temperature, constituents of a material mixture are in temperature and pressure equilibrium by density-pressure iteration algorithm. Combining the adding principle, EOS of a material mixture was calculated by program. In order to verify this procedure, the parameters of state of different deuterium-tritium（DT） and argon mixtures are analysed. For DT doped with a small quantity of argon, the computed EOS agrees well with that of pure DT. Similarly, the EOS of argon with a little DT is in accordance with that of pure argon. The results indicate that the program is feasible.
