在分析岩体水力耦合过程基础上，根据岩体的基本结构及代表性单元体(REV)是否存在提出了建立水力耦合模型的方法。

Based on analyzing HM coupling processes, the conceptual HM coupled models are proposed according to basic structure of rock mass and concept of representative element volume (REV).

为了得到这样一种组织，不仅要检测出镜头和情节这些视频单元的边界，还要提取镜头关键帧和选择情节有代表性的镜头和代表帧。

To achieve such an organization, it needs not only detect the boundary of shots and episodes, but also extract the key frames of shots and select the representative shots and frames for episodes.
