对多流体界面问题守恒和非守恒格式（M）WENO重构方法进行探讨，采用虚拟流动方法并用Level-Set函数捕捉界面的运动变化。数值模拟结果表明本文的数值方法具有较高的分辨率，并能有效地抑制界面附近的非物理振荡。

英文摘要：

Under the conservative scheme, flux components are reconstructed with the component by component versions. Then the quasi-linear systems are solved by the multiple WENO reconstruction based on the 1st order up wind scheme. The level set equation is used to capture the interface movement. Finally the two algorithms are applied to simulate the muti-component fluid flow. Satisfied numerical results have been obtained.
