高职教育生源与就业区域性问题的研究

将生源与就业限制在本地区域范围内 ,曾被认为是高职教育为区域经济发展服务的具体特征表现。这一陈旧观念已成为制约高职教育发展的因素。突破高职教育生源与就业区域性限制 ,对促进区域经济和高职教育持续健康发展具有重要的作用。     

网络时代的现代远程教育

信息技术、网络技术对教育的影响，已经成为很多国际教育会议的热点和主要的议题，也可以说，这个问题不仅是从事这一项事业的人士所关注，也为整个教育界所关注。如果再说得深一点，也有人认为，从工业社会向信息社会的转变，教育形态的转变，在很大程度上是和信息技术的应用，和网络的出现有直接关系的。参加WTO是一个全球化的背景，全球化背景下还有其它很多影响远程教育的因素。本文从三个方面讨论这个问题。一、全球化、学习化、网络化背景下现代远程教育功能的定位问题关于网络对于２１世纪人类生活的影响，这个问题已经不仅是教育…

Quasi 1D modeling of two-phase flow and deposit formation for urea-selective catalytic reduction systems

A quasi 1D model of two-phase flow for a urea-selective catalytic reduction (SCR) system is developed which can calculate not only the generation of reducing agent but also the formation of deposits in the exhaust pipe. The gas phase flow is solved through Euler method, variables are stored on staggered grids, and the semi-implicit method for pressure-linked equation (SIMPLE) algorithm is applied to decouple the pressure and velocity. The liquid phase is treated in a Lagrangian way, which solves the equations of droplet motion, evaporation, thermolysis, and spray wall interaction. A combination of a direct decomposition model and a kinetic model is implemented to describe the different decomposition behaviors of urea in the droplet phase and wall film, respectively. A new 1D wall film model is proposed, and the equations of wall film motion, evaporation, thermolysis, and species transport are solved. The position, weight, and components of deposits can be simulated following implementation of the semi-detailed kinetic model. The simulation results show that a decrease in the exhaust temperature will increase the wall film region and the weight of deposits. Deposit components are highly dependent on temperature. The urea-water-solution (UWS) injection rate can affect the total mass of wall film and expand the film region, but it has little influence on deposit components. An increase in exhaust mass flow can decrease the total weight of deposits on the pipe wall because of the promotion of the mass and heat transfer process both in the droplets and wall film.

My friends＇looks

I have a happy class. In the class, I have three best friends. They are Pen Chao, Bao Xiao and Wang Yiming. Pen Chao is a good student. He has short straight hair. He has two small eyes and a big nose. He wears funny glasses. Somebody thinks that he looks like a panda. But I don＇t think so. He is very short and medium build. He is very clever and he studies very hard.
