-The `PatternProcessFunction` gives access to a `Context` object. Thanks to it,
one can access time related
-characteristics such as `currentProcessingTime` or `timestamp` of current
match (which is the timestamp of the last element assigned to the match).
-For more info see [Time context](#time-context).
-Through this context one can also emit results to a [side-output]({{
site.baseurl }}/dev/stream/side_output.html).
+`PatternProcessFunction`可以访问`Context`对象。有了它之后，你可以访问时间属性比如`currentProcessingTime`或者当前匹配的`timestamp`
+（最新分配到匹配上的事件的时间戳）.
+更多信息可以看[时间上下文](#时间上下文)。
+通过这个上下文也可以将结果输出到[侧输出]({{ site.baseurl }}/zh/dev/stream/side_output.html).
-#### Handling Timed Out Partial Patterns
+#### 处理超时的部分匹配
-Whenever a pattern has a window length attached via the `within` keyword, it
is possible that partial event sequences
-are discarded because they exceed the window length. To act upon a timed out
partial match one can use `TimedOutPartialMatchHandler` interface.
-The interface is supposed to be used in a mixin style. This mean you can
additionally implement this interface with your `PatternProcessFunction`.
-The `TimedOutPartialMatchHandler` provides the additional
`processTimedOutMatch` method which will be called for every timed out partial
match.
+当一个模式上通过`within`加上窗口长度后，部分匹配的事件序列就可能因为超过窗口长度而被丢弃。可以使用`TimedOutPartialMatchHandler`接口
+来处理超时的部分匹配。这个接口可以和其它的混合使用。也就是说你可以在自己的`PatternProcessFunction`里另外实现这个接口。
+`TimedOutPartialMatchHandler`提供了另外的`processTimedOutMatch`方法，这个方法对每个超时的部分匹配都对调用。
