 ## Batch Operations
 
-ABP's distributed cache interfaces provide methods to perform batch get/set methods those improves the performance when you want to get or set multiple cache items in a single method call.

 * `SetManyAsync` and `SetMany` methods can be used to set multiple values to the cache.
 * `GetManyAsync` and `GetMany` methods can be used to retrieve multiple values from the cache.
+* `GetOrAddManyAsync` and `GetOrAddMany` methods can be used to retrieve multiple values and set missing values from the cache
+* `RefreshManyAsync` and `RefreshMany` methods can be used to resets the sliding expiration timeout of multiple values from the cache
+* `RemoveManyAsync` and `RemoveMany` methods can be used to remove multiple values from the cache
 
-> These are not standard methods of the ASP.NET Core caching. So, some providers may not support them. They are supported by the [ABP Redis Cache integration package](Redis-Cache.md). If the provider doesn't support, it fallbacks to `SetAsync` and `GetAsync` methods (called once for each item).

+## 批量操作
+
+ABP的分布式缓存接口定义了以下批量操作方法,当你需要在一个方法中调用多次缓存操作时,这些方法可以提高性能
+
+* `SetManyAsync` 和 `SetMany` 方法可以用来设置多个值.
+* `GetManyAsync` 和 `GetMany` 方法可以用来从缓存中获取多个值.
+* `GetOrAddManyAsync` 和 `GetOrAddMany` 方法可以用来从缓存中获取并添加缺少的值.
+* `RefreshManyAsync` 和 `RefreshMany` 方法可以来用重置多个值的滚动过期时间.
+* `RemoveManyAsync` 和 `RemoveMany` 方法呆以用来删除多个值.
+
+> 这些不是标准的ASP.NET Core缓存方法, 所以某些提供程序可能不支持. [ABP Redis集成包](Redis-Cache.md)实现了它们. 如果提供程序不支持,会回退到 `SetAsync` 和 `GetAsync` ... 方法(循环调用).
