摘要
本文介绍针对固定温度点的热力学函数 (如焓、熵、比热 )综合近似计算法。该方法已成功地用来近似计算温度范围为 10 0~ 2 0 0 0 0 K的 150 0个热力学函数表。用内含近似计算程序包的 TD软件系统对混合物参数进行热力计算的结果证明 ,该多项式在求解多组元系统计算中迭代问题时具有很高的可靠性。
A method for complex approximation of the thermodynamic functions,such as en- thalpy,entropy and heatcapacity,with regard for the fixed points is presented,which has been suc- cessfully used in approximating about150 0 tables within temperature range from10 0 to2 0 0 0 0 K. The results of the thermodynamic calculations of mixture parameters on the basis of TDsoft sys- tem which includes the program approximation Package show high reliability of the polynomials in solving iteration problems for computing multicomponent systems.
