Newton to humanity's contribution is huge, just like Engels said:"Newton as a result of invented law of universal gravitation to establish the science astronomy; As a result of has carried on the light decomposition, but established the science optics; As a result of established the binomial theorem and the infinite theory established the science mathematics; As a result of has known the strength essence, but established the science mechanics".

牛顿对人类的贡献是巨大的，正如恩格斯所说："牛顿由于发明了万有引力定律而创立了科学的天文学；由于进行了光的分解，而创立了科学的光学；由于创立了二项式定理和无限理论而创立了科学的数学；由于认识了力的本质，而创立了科学的力学"。

Based on the analysis of some aspects, such as the approximative algorithm of FOC, the Tustin transform theory and its generating function formula's character, the convergence guarantee of binomial power function by Maclaurin expanding, and the consideration of the limitation of conventional methods, an improved method is proposed to compute the numerical evalution of FOC using PSE and Tustin transform and is further applied to solving the linear FOS.
