n.[数]双向单射
One-to-one onto function is also called bijection. 一对一到上函数称为双映射。
Of course, we use annotations to enable bijection. 当然，我们使用注释来完成双向注射。
Seam introduces the notion of bijection as a generalization of injection. 从客户角度出发，一个特定的无状态的组件的所有实例都可以互换。
In essence, bijection lets you alias a context variable to a component instance variable, by specifying that the value of the instance variable is injected, outjected, or both. 本质上说，双向注射能够让你通过指定实例变量的值是注入，还是注出或者两者都是，从而将一个上下文变量别名为一个组件的实例变量。
The graph isomorphism is to find a bijection between the vertexes of two graphs that preserve the edges.This problem has been paid much attention by many researchers. 图同构问题是指对两个图寻找顶点之间的一个一一映射,使得两图的边在该映射下也保持对应关系,该问题得到许多研究者的关注。
