Another technique that can sometimes be used to find otherwise hidden lapsed listeners is preventing a given listener object from being registered twice with a given event source.
另外一项可以用来找到隐藏失效侦听器的技术是：防止指定侦听器对象在指定事件源上登记两次。
If events are building up in the transport queue (in front of the listener), increase the size of the thread pool for both the listener and the source adapter controller.
如果事件在传输队列(位于侦听器前)中堆积，则请同时增大侦听器和源适配器控制器的线程池的大小。
This means that if the listener logic changes any state in an external data source (database, mainframe, and so on) then these interactions must be treated with an "at least once" delivery paradigm.
这意味着，如果监听器逻辑更改一个外部数据源(数据库、大型机等)中的任意状态，那么这些交互必须通过一个“至少一次”交付范式处理。
To determine the reverberation effects of a single sound we need to determine all the paths between a sound source and the listener .
要决定某一个声音的回响效果，我们就需要确定音源和听者之间所有的路径。
Spatial impression has been regarded as the item ascribable to the quality of apparent source width (ASW) and listener envelopment (LEV) in concert halls.
在音乐厅中，空间印象被认为是由视在声源宽度(asw)以及听者包围感(LEV)所描述的音质。
The weak event pattern can also be used whenever the object lifetime of the source exceeds the useful object lifetime of the listener.
当源的对象生存期超出侦听器的有用对象生存期时，也可以使用弱事件模式。
The following configuration file example shows how to initialize a console trace listener and a text writer trace listener for the trace source that is created in the preceding procedure.
下面的配置文件示例演示如何为在上述过程中创建的跟踪源初始化控制台跟踪侦听器和文本编写器跟踪侦听器。
Whenever the source object lifetime extends beyond the object lifetime of the listener, the normal event pattern leads to a memory leak: the listener is kept alive longer than intended.
如果源对象生存期超出了侦听器的对象生存期，则常规事件模式会导致内存泄漏：侦听器保持活动状态的时间比预期要长。
In effect, the implied reference from the source does not determine whether the listener is eligible for garbage collection.
实际上，来自源的隐含引用无法确定侦听器是否适合进行垃圾回收。
