+### Service
+You can also invoke Loading with a service. Import Loading service:
+```javascript
+import { LoadingService } from 'element-ui';
+```
+Invoke it:
+```javascript
+LoadingService(options);
+```
+The parameter `options` is the configuration of Loading, and its details can be found in the following table. `LoadingService` returns a Loading instance, and you can close it by invoking its `close` method:
+```javascript
+let loadingInstance = LoadingService(options);
+loadingInstance.close();
+```
+If Element is imported entirely, a globally method `$loading` will be registered to Vue.prototype. You can invoke it like this: `this.$loading(options)`, and it also returns a Loading instance.

+### 服务
+Loading 还可以以服务的方式调用。引入 Loading 服务：
+```javascript
+import { LoadingService } from 'element-ui';
+```
+在需要调用时：
+```javascript
+LoadingService(options);
+```
+其中 `options` 参数为 Loading 的配置项，具体见下表。`LoadingService` 会返回一个 Loading 实例，可通过调用该实例的 `close` 方法来关闭它：
+```javascript
+let loadingInstance = LoadingService(options);
+loadingInstance.close();
+```
+如果完整引入了 Element，那么 Vue.prototype 上会有一个全局方法 `$loading`，它的调用方式为：`this.$loading(options)`，同样会返回一个 Loading 实例。
