预处理时间 meaning in English
pre-conditioning time
pre-vacuum chamber
Examples
- Influence of water absorption and pre - wetted method of lightweight aggregate on the workability of concrete
轻集料的吸水率与预处理时间对混凝土工作性的影响 - Due to the simpleness and compactness of meta - information , the time complexities of meta - information based rough set methods is generally lower than their non - meta - information versions . besides , since the meta - information is reusable and can be maintained in a dynamic way , the rough set method can share the same procedure for data pre - processing ( i . e . ,
另外，由于元信息可以保存并能动态维护，基于元信息的粗糙集方法可以共用相同的数据预处理过程(即元信息生成与维护) ，从而减少了数据预处理时间，提高了效率。 - The conventional ways has low efficiency , which result in the application of overlap grid in moving - grid problem , which need re - disposes the interpolating connection in every step in time direction , is very difficult considering the computational efficiency . aim at the above problem in application of overlap grid , this paper using an new manner rooting in analysissitus to put forward a “ method of distinguishing points of intersection ” and develop corresponding computational soft , which could realize the automatic and shape - independent pre - disposal process for overlap grid . to deal with the problem of low efficiency for pre - disposal process in moving - grid , this paper bring forward the “ mosaic ” method and adt method which based on the huge memory of modern computer
对于重叠网格在动网格应用中的计算效率问题,本文通过进一步研究插值信息的高速查询方法,提出不同于传统算法思路,以现代计算机大内存为基础,用计算机物理内存空间换计算时间的” mosaic ”方法以及应用基于二叉树数据结构的adt ( alternatingdigitaltree )方法两类方法,成功的将原处理时间提高了两个数量级? ?即将网格规模在百万量级的重叠网格预处理时间从传统方法的耗时30 60分钟提高到几十秒钟,从而成功解决了这一问题。
