他们的作用是描述，随着状态函数和状态变量的变化， 系统的热力性质如何变化。
So what they do is, they're describing how these thermodynamic properties change, in terms of only state functions and state variables.
建立了基于半哥西分布函数的绝缘油试验评估指标状态函数和考虑指标初始值差异的电气试验评估指标状态函数。
The state function of insulating oil test based on the half Cauchy distribution function and the state function of electrical test considering the initial value differences were constructed.
