In chapter 2, we focus on derivation of the tortuosity models for flow of Newtonian incompressible fluid in two- and three-dimensional porous media with spherical, cubic and plate-like particles by applying the geometrical method. We first present the ideal geometrical models of porous media to show the ideal and representative streamlines based on the assumption that some particles in porous media are unrestrictedly overlapped and hence of different configurations, then the average tortuosity is derived by geometrically and weightedly averaging these representative flow paths.

第二部分采用幾何分析法研究了二維和三維情況下的球形顆粒人人色人人爱爱、立方體顆粒和板狀顆粒多孔介質中流體流線的迂曲度超碰在线wwww，首先給出多孔介質的理想幾何模型，通過分別考慮固體顆粒重疊時国产免费网站看v片在线软件、不重疊時以及粒子的不同排列等情形時的流體流線日本欧美熟妇色一本在线视频，然后對這些理想代表性流線的迂曲度取幾何平均和加權平均，最后推導出流體流過多孔介質的迂曲度解析表達式在线观看日韩午夜福利电影网。

Finally, weightedly averaging the existing evidences, the Dempster-sharer combination rule was used to realize information fusion.

采用最終權重對現有證據進行加權平均，并采用Dempster-shafer組合規(guī)則進行融合日韩三级片欧美A片，從而得到最終融合結果先锋资原吧。

The collision term is two bi-velocity non-dimensionalized reduced ngle tri-velocity model equation is transformed into a bi- h integrating weightedly the non-dimensionalized model equation about the third component of molecule velocity.
