摘　　要：利用最大值和最小值函数探讨两类分段函数的初等性,论证了这两类分段函数是初等函数的判定定理,通过举例说明定理的应用.With maximum and minimum values elementary prosperities of two classes of piecewise function are discussed. The determinant theorem that these two classes of piecewise function are elementary functions, and the application of this theorem is illustrated.
