本文阐述了一套用来计算氦的密度、蒸气压、(?)、内能、熵以及比热等热力学性质的计算机程序。列出了部份程序的框图,推导了有关的基本方程。所采用的状态方程是Mccarty发表的分区域高精度状态方程。文中还列举了本文作者用以减少运算时间的若干技巧。尤其是导出了一个不依赖于状态方程,直接计算焓值的方法,从而使运算的速度又提高了一个数量级,计算精度也有提高。 This article describes a set of computer programs used to calculate thermodynamic properties such as density, vapor pressure, (?), Internal energy, entropy, and specific heat of helium. Lists some of the program block diagram, derived the basic equation. The equation of state adopted is the subregional high-precision state equation published by Mccarty. The article also lists some of the techniques used by the authors to reduce computing time. In particular, a method of directly calculating enthalpy independent of the state equation is derived, thereby increasing the speed of operation by an order of magnitude and improving the calculation accuracy.
