摘　　要：过分析量子级联激光器(QCL)中各量子阱的生热及阱间的热流输运情况,得到它的热输运方程以此为基础类比电路理论建立了等效电路模型,利用计算软件分别进行理论与电路模拟,得到了它的生热特性并对可能影响其生热特性的一些因素进行了分析。By analyzing the heat generation in the quantum wells and heat transportation among wells of the quantum cascade laser （QCL）, the heat transport equation was acquired. After that, comparing it to circuit theory, the equivalent circuit model can be established. Then, using some relevant program, the theoretical and circuit simulation were carried out, and its characteristics of generating heat can be obtained. Meanwhile, some factors were anlyzed which can affect its heat generating characteristics.
