【Abstract】 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 solution is agree to realistic situations.更多还原
