In the thesis, the model for one-phase flow and the mixture model for multiphase flow used were be introduced, and computational software was explained and numerical methods were chose.

论文首先对研究过程中所用到的单相流和多相流混合模型进行了必要的介绍，并对所用的计算软件及模型所采用的数值方法作了说明和选择。

Third, the initial segmentation is refined scale by scale to get the final segmentation of the SAR image based on the posterior probability of classification which is estimated by the mixture model.

最后根据SAR图像的统计性质，利用基于混合模型估计的分类后验概率将初始分割结果逐尺度进行细化得到SAR图像的最终分割。

And in general, if we're going to deal with relatively small deviations from the ideal liquid mixture, the ideal solution, then we can start with a model like this.

通常，如果我们要，处理的相对于，理想液体混合物，理想溶液相差不多，那么我们可以从这样的模型开始。
