查询词典 node

In order to improve present Monte Carlo methods, method changing the node to optimistical orientation corresponding to the system having the lowest energy was proposed, which ensures the grain boundary moving to its curvature center. The new method avoided re-nucleation, and increased simulation efficiency, and made the simulation process more approaching the physics foundation of grain growth. The results show that the grain growth exponent, n=0.478, is close to its theoretic value, and the topological structure accorded with the normal grain growth of the real material.

简要回顾了晶粒长大理论并分析了现有Monte Carlo模拟方法的不足，提出了一个"择优转换"方法，确保节点转换时晶界向其曲率中心移动，以致模拟过程更接近物理基础，避免了重新形核的发生，使模拟效率大大提高，模拟的晶粒长大指数达到0.478，已接近理论值，组织形貌和实际材料正常晶粒长大组织基本一致。

The efficiency of modeling and identifying can be evidently improved by using the techniques of object oriented modeling, interface finite element grid, unit node code auto-numbering and model parameters setting.

Firstly, the three-dimension boundary question and its corresponding variation question concerning the point-source electrical field on a 3-D structure are presented. Secondly, the finite element method is used to solve the variational equation. The study area is divided into many tetrahedral elements. Then, we interpolate with a tri-linear function in each element. So, the variational equation is converted into a linear equation system. Finally, taking into account saving of time, we make use of symmetric successive overrelaxation preconditioned conjugate gradient algorithm to solve large linear system, and obtain the potential value of each node, resulting in the calculation of the apparent resistivity values on the ground surface.
