摘　　要：一般地,分段函数在分段点处的导数要使用导数的定义进行研究和计算,这种方法操作性较差。本文针对一类常见的分段函数,提出了一个简便的计算方法,利用这个方法,这些分段函数在分段点处导数的研究和计算更加容易。Generally, the derivative of piecewise function at the piecewise point should be studied and calculated using the definition of derivative, which is not easy to operate. In this paper, a simple calculation method is proposed for a class of common piecewise functions. With this method, the derivatives of these piecewise functions at the piecewise points can be easily studied and calculated.
