| 摘 要： | 分析了现有的一个连续随机变量函数定理的优缺点．在此基础上，对该定理进行推广，得到的新定理，克服了原定理需要函数是严格单调的这一苛刻条件，推广到逐段单调函数，由此拓广了应用范围．为求解连续随机变量的函数的密度函数，提供了一个新的工具．

| Abstract: | A probe is made into the continuous random variable function theorem about its advantages and disadvanta- ges, on basis of which, the theorem is promoted, and the new theorem thus produced successfully solves the problem that the original theorem is long blamed for its rigid demand of its functions being a strictly monotonic harsh one and thus helps generalize the theorem to piecewise monotone functions, whereby the range of applications has been greatly broadened, and it finds us a new tool for solving the density function of a continuous random variable function. |
