Because of the associative law for addition, we can define multiplication based on addition, a b means a+a+…+a,adding a with b times.

正是由于加法的结合律使得我们可以在加法的基础上定义乘法，就是重复加法的简便运算：a b=a+a+…+a，对a重复相加b次。

Such a commutative law can be enlarged by induction to any two natural numbers: a+b=b+a.

这种交换性可以由归纳法原理推广到任何两个自然数的加法：a+b=b+a。

这使它们通过命令语言中的操作符|来潜在的组合起来： A | B表示一个程序输入A，并输出B。这个系统的定义证实了软件工具的组合性。

This makes them potentially composable through the | operator of the command language: A | B represents a program which will take A 's input, have A process it, send the output to B as input, and have it processed by B .

这使它们通过命令语言中的操作符|来潜在的组合起来： A | B 表示一个程序输入 A ，并输出 B。

If A and B are conjunctive formulas, A∧B is also a conjunctive formula.

若A，B为合式公式，则A∧B也是合式公式。

First,a necessary and sufficient condition that a fuzzy relation R is σ-decomposable is given ,then the solution sets of A and B with AσB=R are obtained.

首先，给出了模糊关系R可σ分解的充要条件，然后在R可σ分解时，给出了使R=AσB成立的A与B的解集。

For example, the module name A.B designates a submodule named "B" in a package named "A".

例如，名为 A.B 的模块表示了名为"B"的包中名为"A"的子模块。

In tetrapolarity mating system,A and B factor is two mating types locus locating different chromosome,only when two single spore mycelium form AαAβBαBβ,then can produce to dikaryon and complete whole sexual life history.Study according to the Eger.

在四极性交配系统中，A和B因子分别对应位于不同染色体上的两个交配型位点，两个单核菌丝相遇，只有当它们形成A1A2B1B2或者AαAβBαBβ型时，才能产生具有锁状联合的双核体，完成整个有性生活史。

In OWE-SOJ test, a fluffy colony without clampconnection formed in the A=B���mating interaction where nuclear migration occurs, whilea barrage colony without clamp connection formed in A≠B= interaction where nuclearmigration do not occur. The two colonies could be distinguished clearly from each other.

而在OWE-SOJ试验中，发生核迁移的A=B≠交配反应形成无锁状联合的绒毛状菌落，而不发生核迁移的A≠B=反应形成无锁状联合的栅栏型菌落，两种菌落可以清楚地区别开来。

Values of 2sin A in the form a b+ or a b-, where a, b are rational numbers.
