This is found to result from the existence of negative orography in this low-resolution model. It is shown that, over the grid-points where orography height is negative, there exists false sensible heat source that leads to warmer temperature and higher geopotential height.

利用位涡的特性，研究并模拟了大气流场在短时间尺度上对非绝热加热的响应，并提出了"过流"的概念：在加热层顶，即使非绝热加热消失，仍存在上升运动，反气旋涡度环流和冷中心。

牙齿间的牙龈乳突也遭侵蚀，而且被一层灰色坏死组织覆盖。

It becomes more difficult to manage, integrate and share the control system real-time data when we set up the industrial real-time database because of complicated affair between every department and isomeric character of the system. A three-level-structure model and the method to establish database is provided based on CORBA criterion with its character of being regardless of programming languages, hardware platform and network protocol . A universal real-time database faces multi-system is also set up by learning the distributed criterion, it can realize the request broker , and the application software can visit the database pellucidly ; Thus the power station simulation model can be linked with the control system such as infi90 , ovation and be made use of the control object , a closed simulation and control experiment system is set up. Further more we can build an integrate automatic experiment platform from the simulation object of power plant to the process control and the to SIS.
