In other words, f respects addition, multiplication and identity element . 换言之,F保持加,乘法和单位元。
If we consider the integers with ordinary multiplication we have closure, associativity, and identity element . 如果我们考虑整数集且用通常的乘法,我们有封闭性,可结合性,和一个单位元。
Bearer capacity identity element bc ie 承载能力标示单元
In other words , f respects addition , multiplication and identity element 换言之, f保持加,乘法和单位元。
Let k be an algebraically closed field and a be a commutative associative algebra with an identity element 1 设a是代数闭域k上具有单位元1的交换结合代数, d是由a的可交换的k -导子所张成的k -线性空间。
But the results above all base on the fact that semigroups have identity elements . thus it is relatively has certain confinement 但以上的结果都建立在半群含有单位元的这个基础上,这相对就有一定的局限性。
A kind of probability sample in which a set interval is applied to a list often population to identity elements included in the sample ( e . g . , picking every 10th name ) 一种概率抽样.以一定的间隔来从人口名单中抽取所需的样本(如:每隔10个人抽取一次)
In order to break the confinement , in this paper we manage to study semidirect products of semigroups regardless of identity elements . that is , we get rid of the especially important condition that semigroups have identity elements 为了突破这一局限性,本文就力争在一般的半群上研究其半直积,即去掉单位元这个特别重要的条件。
By describing semidirect products and structures and congruences , we can manage to obtain some structures and congruences on this kind of semigroup . it is under the condition that semigroups have identity elements that most of researches on semidirect products 因此我们可以通过去刻划半群的半直积及其结构与同余,来刻划这类半群的某些结构特点及其上的同余。

百科解释
In mathematics, an identity element (or neutral element) is a special type of element of a set with respect to a binary operation on that set. It leaves other elements unchanged when combined with them.
