摘　　要：介绍阶梯杆压弯问题的传递矩阵法．将阶梯杆分成单元，对单元进行受力分析和变形分析，得出反映这一物理现象的常系数线性微分方程．利用该方程的初参数解，构成传递阵．传递矩阵法，采用矩阵形式来表达，使求解过程大为简化，亦适合上机计算．The transfer matrix method for the compressed bending with stepped bar is introduced. At first,the stepped bar are divided into many elements: then force and deformation of all the elements are analysed and a linear differential equation with constant coefficients for reflecting the physical phanomena is obtained a transfer matrix is construced by using the initial parametric solution of the differential finally. The transfer matrix methed is expressed in the form of the matrixes, which greatly simplifies the solution of the compressed bendings with stepped bar and is suitable for the calculation by the computers.
