摘　　要：利用方块脉冲函数的运算性质直接求解弹性压杆的能量泛函极值，得到计算弹性压杆临界载荷的一种新的数值方法．这种方法具有计算简洁、便于计算机处理的特点，有很好的工程应用价值．The minimum value of the functional analysis of the energy in elastic compressed bars are directly solved by means of the properties of the block_pulse functions. A new numerical method for calculating the critical load of elastic compressed bars is obtained. This method is characterized by its convenience of calculation and computer processing. Hence, it is of great value in engineering application.
