摘要
非稳态导热问题的数学模型为偏微分方程组。给出了利用拉普拉斯变换法求解非稳态导热问题的方法步骤,并采用此方法对边界条件为恒定热流和变热流两种情况进行了求解。
The mathematical model for unsteady state heat condition is partial differential equations. The methods and steps of Laplace transform applications in solving unsteady state heat condition problem is presented. Furthermore ,boundary conditions for the constant heat and variable heat two cases were solved through this method
