intersection of two sets 中文意思是什麼

intersection of two sets 解釋
二集合的交集
  • intersection : n. 1. 橫斷，橫切；交叉，相交。2. 【數學】交集。3. 交點，交叉線，十字路口。4. 邏輯乘法。
  • of : OF ＝Old French 古法語。
  • two : n. （pl. twos）1. 兩人；兩個東西，一對。2. 二的記號。3. 兩點鐘。4. 兩歲。n. -ness
  • sets : 集合
  1. It belongs to the intersection of two sets if it causes both the unary

    ） ；如果它使兩個一元
  2. A variable is sampled in a certain increment, and introduced into the equations. there are two sets of any two equations to be solved. the real solutions of the two sets are protracted in spatial coordinate system to obtain two curves, so that the intersection points of the two curves can be found as the solution of the original equations

    針對所得三元高次多項式方程組，採用數學分析軟體mathematica編製程序，以一定的步長增量，在一定范圍內取一個變量的值，並將其代入方程組中，求解其中一個方程分別與另外兩個方程聯立的方程組的解，將得到的實數解繪製成兩條空間曲線，其交點即為原三元方程組的解。
  3. This can be worked out to taking the union of the two sets and then removing from it the elements belonging to the intersection of the two sets

    這可以取兩個集合的並集，然後從中刪除屬于兩個集合的交集的元素得到。
  4. The exact express of the intersection and union of the fuzzy sets defined by the rough membership function is given. two extension model of rst are introduced and their characters are discussed. we also discover the changes of the upper ( lower ) approximation after the attributes were added to or removed from the original attribution set

    首先得到了由粗糙隸屬函數所定義模糊集的交與並的確切表達，改進了以往文獻的結果；其次，提出了兩種粗糙集的擴展模型，並對這兩種模型的性質進行了討論；最後，得出了屬性集增加或刪除屬性後集合的上下近似的變化關系。
