numerical approximation meaning in Chinese
近似数值
数值近似法
Examples
- Main object of the first chapter is to investigate adaptive mesh re - distribution methods . successful implementation of the adaptive strategy can increase the accuracy of the numerical approximations and also decrease the computational cost
移动网格方法，作为自适应方法的一种，主要是为了解决发展方程的计算问题而设计的方法，本文第一部分主要研究的是一种自适应网格重新分布方法。 - And then we found and testified two examples , in which the connections in n - variable mean fam - ily , countable mean family and continuous mean family are shown . the theory in this paper prepares for the further application in convex analysis , numerical approximation , cagd , probability and statistics . etc
文中还给出了连续平均族的两个具体的实例，对这两组平均族进行了证明，并找出了其中蕴含的连续平均族与可数平均族、 n元平均族之间的联系等等 - In the space , wavelet approximation formula and sampling formula are gived and these are simple and easy for calculation . it is a new attempt to establish mra in the reproducing kernel space . this not only makes up existing researchful defects but also gives a better method to resolve numerical approximation problems and it further enriches the reproducing kernel theory and wavelet method . this provides more applied method for resolving numerical approximation problems in the space which is often used in the engineering
在再生核空间中建立的多尺度分析方法是利用再生核工具探讨小波理论的又一次大胆的尝试，它不但弥补了现有研究的缺憾，而且给出了解决数值逼近问题的一个新思路，进一步丰富了再生核理论，充实了小波方法，这为在工程中常用的空间中解决数值逼近问题又提供了一种较为实用的方法。
