boundary n. 边界,疆界,限界 (between);(球场)边线;界标;界限,范围,分野。 aboundary dispute 边界纠纷。 the boundary between Canada and the United States 美加国界。 boundaries on all sides 四方辐辏之所,四通八达。
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。
