approximate boundary meaning in Chinese

概略界线

The comprehensive treatment of a variety of approximate boundary conditions , such as : standard boundary condition ( sibc ) , generalized boundary condition and exact boundary condition , applied to electromagnetic
阻抗边界条件为分析涂敷目标的散射特性、评估不同涂敷形式的效果优劣提供了简捷而有效的计算方法。
In this part , inner and outer approximate boundaries are presented for the first time and their properties and processing idea are studied . and then we generalize the conceptions of inner and outer approximately definable sets . next , chapter 3 puts forward a new data filtering method based on both binary information system and degree of rough membership
在此基础之上，第二章讨论了粗糙边界问题? ?一类不可区分性不确定问题? ?的近似处理，首次提出了内外近似边界的概念，并进行了相应的性质讨论，然后给出了近似精确问题的三种近似处理思想，最后将内外近似精确集的概念推广到程度近似精确集。
