Semicolon problem comes out from Ecmascript standard inner tube actually, the context that inserted semicolon principle automatically in Es standard to break grammar has nothing to do quality, so implementation rises very troublesome have 3 kinds of means of settlements: 1, completely handwritten Parser2, modification grammar (in regarding terminative Fu Fang as to enter generation type line feed accord with), this kind of method is the most troublesome 3, modification ParserGenerator produces a mistake to restore code, whether is be being judged when encountering solecism caused in the absense of semicolon, whether to if be,satisfy in judgement insert semicolon principle (if encounter right big bracket or line feed) it is the most convenient that implementation of the 3rd kind of method rises, but the Parser support mistake that needs ParserGenerator generation restores.

分号问题其实是从Ecmascript标准里带出来的，es标准中的自动插入分号原则打破了语法的上下文无关性，所以实现起来很麻烦有三种解决方法：1，完全手写Parser2，修改语法（把换行符作为终结符放入产生式中），这种办法最麻烦3，修改ParserGenerator产生错误恢复代码，在遇到语法错误时判断是否是由于缺少分号引起的，如果是在判断是否满足插入分号原则（如遇到右大括号或者换行）第三种办法实现起来是最方便的，但是需要ParserGenerator产生的Parser支持错误恢复。

The major implementations of the developed model include: Pseudo-spectral and finite-difference schemes are employed to approximate the spatial-differential operators in the horizontal and vertical directions, respectively. A second-order Runge-Kutta method is adopted to integrate in time for the velocity field and the free-surface elevation. The solenoidal condition of the velocity field is satisfied by solving the transformed pressure Poisson equation. A modified secant method is used to accelerate the iterative solution of the non-separable Poisson equation.
