原始的二分法只能求取单解方程。本程序基于二分法，通过自动划分待求解区间，得到多解方程在指定区间内的所有解。(The original dichotomy can only solve the equation of single solution. This program is based on dichotomy, through the automatic division of the interval to be solved, the solution of multiple solutions in the specified interval of all solutions.)
