摘要
由实验测得体胀系数α及压强系数β求物态方程,这主要是如何求全微分的积分问题。这是因为物态方程是态函数,所以其中任一参量的微分表达式一定是全微分。求解这类问题,要抓住两个关键:如何建立微分式与判别全微分式;如何求全微分的积分。这里讨论了四种求解方法:常数变易法;凑成全微分法;与积分路径无关法;与昂尼斯气态方程比较法。
Experimental measurements from the appropriate pressure coefficient of expansion coefficient α and β Find the equation of state,mainly to the integral of the differential perfectionist.This is because the equation of state is a state function,so any parameter must be the total differential differential expression.Solving such problems,we must seize the two key： how to create a differential type and determine the total differential type;how to solve the total differential of the integral.Four methods for solving are discussed here： constant variation;make up total differentiation;and integral path-independent method;comparison with Ang Nisi gas equation.
