说明：  使用5阶WENO格式，3阶RK格式，LF通量分裂，对一维Burger s方程进行求解。所得结果可以与《Weighted Essentially Non-Oscillatory Schemes》1994中结果进行对比
(Using five order WENO scheme, the third-order RK format, LF flux splitting of one-dimensional Burger' s equation is solved. The results can be used with " Weighted Essentially Non-Oscillatory Schemes" 1994 the results were compared)
