摘 要: 为了简洁快速完成牛顿二阶法的求解,利用三维海森矩阵截面给出一个简单直观的牛顿二阶法中二阶导数项分解降维求解公式的推导方法,即在牛顿法求解的功率修正量计算中增加一项增量功率修正量的求解。这一思路解决了牛顿法数学推导繁琐的问题,使之很容易按照诱导得到牛顿二阶法求解的结论。 In order to simply and rapidly obtain the solution to the Newton second-order method, a simple method for the calculation of the second-order derivative term in the Newton method, specifically, by adding an increment term into the power revision of the method, is presented using a three-dimensional Hessian matrix cross-section. This method can eliminate complieated mathematical derivation and can be used to obtain the solution to the Netwon second-order method.
