Chapter 5 considers two mechanization algorithm of jacobian function solutions based on sine - gordon and sinh - gordou equations 在解决问题的过程中吴代数消元法是最重要的基本工具。

We call above two mechanization algorithm as jacobian function expension method . the jacobian function expension method is an effective method than the sine - consine method and the sn - cn method 称之为雅可比椭圆函数扩展法，它是一种比sine - cosine方法和sn - cn函数法，双曲函数法更有效和简单的方法。
