【摘要】 分析了M-H Eos中常数b的物理意义,得到它是分子体积影响的结论,并由此结论将该常数根据经验修正为温度的函数。按照M-H Eos确定常数的方法重新推导了其它各常数的表达式,得到修正常数b后的M-H Eos。最后,将该Eos编制程序,并通过实际计算验证了修正后的M-H Eos。结果表明,修正后的Eos在计算准确度上有所提高,修正常数b后的M-H Eos更加合理,并提高了计算准确度。更多还原

【Abstract】 The physical meanings of constant b of M-H equation of state (1955), which is the effect of volume of molecules is analyzed. According to the result, the constant b to be a function of temperature has been modified and a modified M-H equation of state has been obtained. In term of the rule of determination of constants of M-H equation, the forms of all constants of the modified equation has been derived. At last, a program on Eos has been made and the modified the M-H equation has been validated. The results showed that the accuracy of calculation has been improved. In order to improve the accuracy of calculation of M-H equation of state, it is of importance to study the physical meanings of constants of M-H equation of state.更多还原
