-# Custom Blocks
+# 自定义块
 
-You can define custom language blocks inside `*.vue` files. Loaders applied for a custom block are matched based on the `lang` attribute of the block, the block's tag name, and the rules in your webpack config.
+在 `.vue` 文件中，你可以自定义语言块。应用于一个自定义块的 loader 是基于这个块的 `lang` 特性、块的标签名以及你的 webpack 配置进行匹配的。
 
-If a `lang` attribute is specified, the custom block will be matched as a file with the `lang` as its extension.
+如果一个 `lang` 特性被指定，则这个自定义块将会作为一个带有该 `lang` 扩展名的文件进行匹配。
 
-You can also use `resourceQuery` to match a rule against a custom block with no `lang`. For example, to match against `<foo>` custom blocks:

-If a matching rule is found for a custom block, it will be processed; otherwise the custom block will be silently ignored.
+如果找到了一个自定义块的匹配规则，它将会被处理，否则该自定义块会被默默忽略。
 
-Additionally, if the custom block exports a function as the final result after being processed by all the matching loaders, that function will be called with the component of the `*.vue` file as a parameter.
+额外的，如果这个自定义块被所有匹配的 loader 处理之后导出一个函数作为最终结果，则这个 `*.vue` 文件的组件会作为一个参数被这个函数调用。
