局部域的英文
例句与用法
- Lbie , based on the local boundary equation , adopts the traditional moving least squares ( mls ) approximation which depends on only the values of the nodes in the domain of the problem or along its boundary . the whole process of integration is carried on over a local domain or its local boundary centered at the node in question . the local boundary equation can be rewritten to represent the values of the unknown function at the point of interest , and the essential boundary conditions can be directly and easily enforced by using the green formula and the characters of the dirac function
它以局部边界积分方程为基础，采用移动最小二乘近似函数，从而只需要分布在问题域内及其边界上的节点的信息值，无需划分单元；整个积分是在以节点为中心的局部域及其边界上实现，所以不需要背景积分网格；借助于格林公式及dirac函数的性质，将局部边界积分方程转化为所考虑点的未知函数的边界积分表达式，便于直接施加本质边界条件。
百科释义
在数学上，局部域是一类特别的域，它有非平凡的绝对值，此绝对值赋予的拓扑是局部紧的。局部域可粗分为两类：一种的绝对值满足阿基米德性质（称作阿基米德局部域），另一种的绝对值不满足阿基米德性质（称作非阿基米德局部域）。
