1. Here the TSO (Time Stamp Order) and lookahead mechanism is for the conservative asynchronous events, the tie-breaking mechanism is for the conservative synchronous events and the Rollback mechanism is for the optimistic synchronous events.
对于保守非同步事件的管理采用时戳（TSO）与非零前瞻量（Lookahead）机制进行管理；保守同步事件的管理采用tie-breaking机制：乐观事件采用回卷（Rollback）机制。
