摘　　要：用广义函数导出和建立了汽轮机阶梯式变厚度轮盘的定常热传导微分方程，用初参数及Ｗ算子来表述该方程的通解，用传递矩阵法来求解该问题的温度场及热应力。最后附有算例，以说明本法的应用。By using generalized functions, the differential equation of steady heat conduction is derived and established for a stepped disc of steam turbine. The general solution of this equation is expressed by initial parameters and W operator. To use matrix method, the temperature field and thermal stresses are calculated for this problem. As an application of the method, an example is giv- en.
