不过，请注意，被调用的伙伴最后同样也可以成为客户机—流程调用伙伴上的某个操作以请求某种服务这种情况是可能出现的。
Notice, however, that invoked partners may end up being clients as well — it may be the case that the process invokes an operation on the partner to request some service.
异步交互的主要支持机制如下：客户机调用流程上的某个操作以请求某种服务。
This is primarily how asynchronous interaction is supported: the client invokes an operation on the process to request some service.
另一方面，服务器端流程实施可以在与主操作相同的存储库事务中运行；客户端流程实施则不是事务性的。
On the other hand, server-side process enactment can run in the same repository transaction as the main operation; client-side process enactment is not transactional.
