MGM is introduced to solve field distributions in 3-D electron optical systems. The difference equation, the discrete form of Laplace's equation, is deduced in 3-D Cartesian coordinates. In view of the smooth effect, MGM combines Gauss-Seidel iteration with a technique known as coarse grid correction. Formulae for restriction and prolongation are deduced and expressed in terms of tensors.

When a user selects an object, a vertical line extends from the center of the object to the grid.

当用户选择一个对象后，从对象的中心有一条垂直线扩展到网格。

Meanwhile, complex model results in aberrant grid which leads to wrong simulation results.

同时复杂的模型会使计算量急剧的增加，过于复杂的模型也会导致网格的畸变，导致错误的仿真结果。

The absolute frequency is a function related to the traditional frequency and how long the certificate has been used since the time it was used the last time. In the paper the authorization module based on the attribute certificate is implemented using the C++ language. It also has been added to the GT4 to provide to the certain Grid application with a new authorization schema.

相对使用频率即传统的使用频率，绝对使用频率是对象最后一次被使用后经历的时间与相对使用频率的函数； 5）授权决策模块本文采用C++面向对象设计语言实现了基于属性证书的网格授权模块，并在Globus Toolkits 4.0环境下通过加入该授权模块为特定网格应用提供该授权机制。

This extension allows a much more efficient grid generation process and makes grid generation for topologically similar configurations quite easy.

并进一步提出了网格生成宏和网格生成模板等概念，以提高网格生成过程的效率和自动化程度，降低网格生成对用户专业技术知识的要求。

The previous researches have been done experiments mostly in the Water tank. In order to simulate turbulence of flow in river and research its characteristics, the characteristics of turbulence are studied by experiments in the water channel with ADV technique. The research results indicate that R.M.S. velocity linearly relates to the oscillating-grid frequency; R.M.S. velocity decays by power exponent relates to the distance from the grid midplane; and the relationship between the geometrical factors and the free movement space of water is direct proportion.
