The model equations with tbree-dimensional, time-dependent, nonlinear Navier-Stokes equations are transformed by *** the basis of the process splitting technique, the fluid flow problems are divided into two parts:the vertically-intopated equations (external mode) and the vertical structure equations(internal mace). The first set of equations being the propagation of the tidal weves and the ADI numerical scheme has ben chosen to solve them. Conerning the vertical structure equations, they are solved by means of leapfrog stepping *** main features of the tide and associated tidal current in the Bohai Sea are examined with this 3-D *** have a good reproduction of vertical structure, the column is divided into 10 layers and the M2 tidal current is computed in detail. The simulation reveal the spetial structure and some important characteristics of the tidal current of the Bohai Sea. The application of the 3-D madel to forecasting of the tidal current in the Bobal Sea has been Performed as an illustration.

To examine the circulation in shallow water with tidal flat, a finite element model for the numerical solution of the shallow water equations was developed by means of standard Galerkin's method. The domain computed was covered with triangular finite elements, and water elevation and velocity were approximated by linear interpolation functions, and the lumped coefficients were used to substitute for solving the high order algebraic equation system. The time-dependent land-water boundary changes are treated mathematically by interrelating the location of the land-water boundary with the instantaneous tidal level. The implicit scheme was adopted for the terms of the bottom friction and the Coriolis effect in the motion equation so that the numerical stability of the model has been *** model was applied to the tidal current on shoaling water with large tidal flat off Pikou, and a comparison between observed and calculated values showed good agreement, the flow pattern being reproduced. The result shows that the model is able to be widely applied to predicting the circulation in shoaling waters.

Reversibility of quantum entanglement state

第十八届全国量子光学学术会议

作者：杜少将 Hai-Ran Feng Feng Han lianwu yang Yu-Jun Zheng 济宁学院 Department of Physics and Information Engineering Ji-ning University School of Physics Shandong University

Based on the theory of balance between information gain and reversibility to study the entanglement intensity of quantum state. Using the theory to study entanglement state, taking two-body entanglement state as an example, to analyse the trade-off relation and calculate entanglement intensity after weak measurement operation and proper reversible operation. The result indicate that entanglement intensity can practically reverse to its original state. This protocol can help us to get some information from quantum system and reverse the a destruct quantum entanglement system.

高校的学生工作与教学工作的划分,使得这二者之间出现了一些尚未覆盖的真空地带和人为导致的问题。针对这些问题,提出建立"大学工"模式,通过打造多元身份的教学队伍、形成学工与教学的信息通路、有针对性地在学生工作中引入教学资源等方式来实现高校育人的根本任务。具体做法为由教师担任专业指导老师、本科生导师、职业规划导师、创新创业指导老师、社会实践与志愿服务指导老师、咨询专家或社团指导老师等多种角色来融入学工系统。
