An object module is a machine-language translation of a source module, and may include references to other subroutines. 目标模块是由源模块转换成的机器语言程序，它可以包括其它子程序的调用。
Linkers fix up references between these object modules, where a routine or data structure referenced in one module actually exists in another module. 连接器负责解决目标模块之间的引用，例如一个模块中引用的例程或数据结构事实上在另外一个模块之中。
