Because when all is said and done, you will have tried some finite number of things before you succeeded, Every time you made a mistake you eliminated one of those things and are one step closer.
因为在成功前，当该说的说了，该做的做了，你所要进行的尝试是有限的。每犯一次错误，那些所要做的尝试就会减少一个，从而你离成功也就更近一步。
The algorithm USES multi-time steps to replace single time step in traditional non-uniform finite-difference time-domain (NU-FDTD) method to enhance the computing speed.
该方法通过应用多个时间步长替代传统非均匀时域有限差分(NU - FDTD)法的单一时间步长的算法来提高计算速度。
For every time step, the two dimensional Laplace's equation is solved by a finite-element method, so the potential distribution over the foil is given.
