| 摘 要： | 本文先将倒虹吸管的管径计算公式整理成等式左边只含管径的一次方法，右边含有管径高阶非线性的迭代函数，然后证明该迭代函数收敛，最后利用数学迭代原理给迭代函数右边赋初值，计算左边的管径。继续迭代下去，就能求出倒虹吸管的管径。

| Abstract: | This paper at first arranges the formula of computing the diameter of a siphon pipe as a simple iterative function, then proves its restraint based on the restraint theorem, and illustrates steps of computing the diameter with this method. Some examples are given in the last of this paper. |
