Aiming at bottom roof caving and support impact problems induced with abrupt large scale caving upper roof in face 21303 of Daliuta mine, this paper put forward the motion parameter at roof caving and calculation formula of roof shear breaking force with the help of theorem of momentum, theorem of moment of momentum and D' Alembert principle. Roof caving process was simulated by Ansys Ls-DYNA program, and maxim impact force was got. The theoretical research outcomes in the paper were applied in face 21303 of Daliuta mine, and were accordant with actual observing status of roof caving process.

针对神东煤炭公司大柳塔煤矿活井21303综采工作面，上层采空区顶板突然大规模垮落对下层顶板及支架的突然冲击问题，文章采用动量定理、动量矩定理、达朗伯原理推出了顶板垮落瞬间的运动量及顶板切顶垮落所需要的剪力值计算公式，用ANSYS LS-DYNA程序对顶板垮落过程进行了数值计算，得到了最大冲击力，在大柳塔煤矿活井21303综采工作面对顶板垮落特征进行了实际观测和理论成果验证。

The author concludes that the last deglaciation climate variation in the proxy records for the east Asian monsoon has an asymmetric shape; the warming events are abrupt and the cooling events are gradual.

In the video segmentation method based on DEMD, the intrinsic mode function with the lowest frequency is discarded and a simple and effective motion compensation method is adopted. As a result, the video segmentation method is no longer sensitive to abrupt change of luminance, object motion in shots, motion and zoom in/out of cameras, so that the precision of detecting shot boundaries is improved.

基于DEMD的视频分割方法除去视频帧中反映图像内光照分布与能量的最低频率固有模态函数(intrinsic mode function，IMF)分量，并选择一种简单有效的运动补偿方法，解决了传统基于直方图方法对光照突变、镜头内物体运动和镜头运动及拉伸的敏感问题，减少了镜头边界识别的误检率，在保证召回率不受影响的前提下提高了视频分割的精确度。

My mother suggested I teach David what I know about music, and received a very abrupt and derisive snort down the phone.

我母亲提议我自己教大卫音乐，我在电话上毫不客气地嘲笑了这个主意，而且很干脆地拒绝了。

From the beginning of 20 centuries to the 80's, for alleviating the destructibility to economy, politics , and the international environments in the abrupt affairs, the study of crisis management in western has achieved an important breakthrough both in the political science and in the international relation study, and then it gradually enlarges its service from business enterprise to government.

20世纪初期，随着社会分工的强化，工人和资本家之间的矛盾激化，劳资关系的恶化使企业经常碰到一些不可预测的突发性事件，严重影响企业的生存和发展，从20世纪30年代起，理论界开始研究企业危机管理，到20世纪60至80年代，西方危机管理理论在政治学和国际关系领域出现了突破，逐渐由对企业危机管理的研究转向政府危机管理研究。

According to the climate data observed by 19 weather stations in Hexi corridor from 1960 to 2005, the annual and seasonal agricultural climate resources, including light, heat and water and so on, are diagnostically analyzed by using the method of climate changing tendency, and the abrupt changes of critically agricultural resources factors are analyzed by approach of Mann-Kendall.
