讨论了几种线性情形下的热传导方程的局限性 ,在此基础上考虑到热传导方程中导热系数、比热容、密度与温度的关系 ,热传导方程变为非线性热传导方程 ,其解的行为与实际相符

At first,Limitations of the general heat conduction is discussed and then,nonlinear heat conduction equation are derived.When we consider that thermal conductivity,specific heat capacity and density are depondent of temperature.At last,the solution of the nonlinear equation is obtained and the action of the so...
