摘　　要：给出了分段线性函数族的定义和有关的运算性质，利用这些性质得到直接求解变分问题的一种新的数值方法。本文算法较之Ｗａｌｓｈ函数算法和方块脉冲函数算法具有更高的计算精度。The definition of the Segmental Linear Functions and some operational properties are given. By means of the properties,a new numerical method for direct solving variational problems is obtained. This method is much better than that of Walsh Functions and Block-pulse Functions in calculation with accuracy.
