是温度的函数,它只是温度的函数,不管是什么气体。
The only function it is -- it doesn't care where the gas is. It only cares where the temperature is.
当介质的导热系数是温度的函数时,热传导方程是非线性偏微分方程,作者采用基尔霍夫变换把它变成拉普拉斯方程,于是可以找到原问题的近似解析解。
The nonlinear equation of heat conduction is transformed into a Laplace's equation by applying the Kirchhoff transformation, and an analytic approximate solution of the equation is derived.
数学模型允许我们计算温度的上升作为上升的函数,结果表明答案可能是肯定的。
Mathematical models that allow us to calculate the rise in temperature as a function of the increase indicate that the answer is probably yes.
The only function it is -- it doesn't care where the gas is. It only cares where the temperature is.
是温度的函数,它只是温度的函数,不管是什么气体。
are all functions of state and parameters that we can control like temperature and pressure.
公式里面的全部都是态函数,我们控制态函数的参数比如温度或者压强。
So that you could see that for the ideal gas, u would not be a function of volume, but only of temperature.
所以我们可以看到对理想气体,内能不依赖于体积,而仅仅是温度的函数。
