It's found that, this theory can predict both"miscibility gap"and anisotropical phase separation of polymer blend, while the two different previous theories, that is the pure thermodynamical one and hydrodynamic one, could only predicts one but not both of them.

由于综合考虑了剪切的热力学以及流体力学影响，原来只能由纯热力学理论和&二流体&模型分别预测的复杂表观相图（例如Miscibility Gap）以及各向异性相行为都可以通过该模型加以预测和解释。

After that, a numerical model about Zhejiang shore tide is established by mike21 program. After validating the good agreement between simulated results and observed ones, the planar hydrodynamic flow of this ocean area is analysed in detail. Then co-tidal and co-range chart of each main tide is drew based on the computational result. It can be found that each co-tidal and co-range chart that is based on the simulated result is suitable to the co-tidal and co-range chart that is deduced from autoptical data, besides, the modle co-tidal and co-range chart can perfect the co-tidal and co-range chart from autoptical data where autoptical data is too hard to get .

在这之后，使用MIKE21水动力模块建立起浙江近海海域潮波模型，在模型潮位、潮流流速流向验证均合理的基础上，分析了计算得到的二维水动力流场，最后将模拟结果绘制出浙江近海M2、S2、N2、K1、O1主要分潮的同潮时图，并将其与实测同潮时图比较，发现各分潮等振幅线及同潮时线相同或相近值的等值线位置及走势基本一致，而且模拟得到的同潮时图对实测资料覆盖不到的海区做了适当补充。

基于对气固并流上行和并流下行流体力学行为的分析，本文建立了一个简单的k—ε湍流模型。

Results reveal that the development and dissipation of the dynamic pore pressure are coinstantaneous and this makes both the positive and negative dynamic pore pressure and seepage force alternate with time. Repetitive hydrodynamic pumping and sucking during moisture damage is proved.

结果表明，水压的产生和消散在轮载作用过程中同时存在，导致面层内正负水压力及渗透力随时间交替出现，这证实了水损坏过程中的水力反复泵吸作用。
