The first generalization is that the expansion of solutions of equations is generalized to negative exponent, and negative exponential elliptic function solutions are obtained.
第一种推广为，将方程解的展开式扩展到负指数，可以求得方程的负指数的椭圆函数解。

Nonlinear directly estimating formula for exponential curve which, through fixed point, was derived, by using first order approximation of Taylor expansion.
