The characteristic approximation is used to handle the convection part along the direc-tion of fluid namely characteristic direction to ensure the high stability of the method in approximating the sharp fronts and reduce the numerical diffusion; The mixed finite element spatial approximation is employed to deal with diffusion part and approximate the scalar unknown and the adjoint vector function optimally and simultaneously; In order to preserve the integral conservation of the method, we introduce the modified characteristic method.

该方法对方程的对流部分沿流体流动的方向即特征方向离散以保证格式在流动的锋线前沿逼近的高稳定性，消除数值弥散现象；对方程的扩散部分采用最低次混合有限元方法离散、同时以高精度逼近未知函数及未知函数的梯度；为保证方法的整体守恒性，在格式中引入修正项。

Vectorgraph can be converted to a bitmap, but in turn bitmap converted to vectorgraph technical comparison difficult to achieve, a lot of graphic design software that support the use of pixel figure converted to vectorgraph, a general description of the software for free vector function realization, so that we can on the basis of vectorgraph to do the editing, but this kind of conversion sometimes is time-consuming, and sometimes does not achieve the expected results, it is generally used for relatively simple bitmap, or you would like some special effects.

矢量图可以转换成位图，不过反过来把位图转换为矢量图技术上比较难实现，很多图形设计软件都支持将像素图转换成矢量图性，一般可用矢量软件的描摹功能实现，这样我们就可以在矢量图形的基础上再做编辑，但这样的转换有时候会很耗时，有时候并不能达到预想的效果，一般用于比较简单的位图，或者想要表现一些特殊的效果。
