-This section covers all __variables__ available in code compiled with webpack. Modules will have access to certain data from the compilation process through `module` and other variables.
+本章节涵盖了使用 webpack 编译的代码中所有的 __变量__。模块将通过 `module` 和其他变量，来访问编译过程中的某些数据。
 
 
 ### `module.loaded` (NodeJS)
 
-This is `false` if the module is currently executing, and `true` if the sync execution has finished.
+`false` 表示该模块正在执行， `true` 表示同步执行已经完成。
 
 
 ### `module.hot` (webpack-specific)

+表示 [模块热替换(Hot Module Replacement)](/concepts/hot-module-replacement) 是否启用，并给进程提供一个接口。详细说明请查看 [模块热替换 API 页面](/api/hot-module-replacement)。

 ### `module.exports` (CommonJS)
 
-Defines the value that will be returned when a consumer makes a `require` call to the module (defaults to a new object).

-This variable is equal to the default value of `module.exports` (i.e. an object). If `module.exports` gets overwritten, `exports` will no longer be exported.
+该变量默认值为 `module.exports`（即一个对象）。 如果 `module.exports` 被重写的话， `exports` 不再会被导出。
