　　为保障三峡船闸级数转换及叠梁门落放的安全运行，长江三峡通航管理局在转换运行级数之前及时发布了通告，合理安排换级期间的调度工作。在运行方式转换过程中，技术人员对各闸室的初始水位进行了调整，确保三峡船闸级数转换工作的顺利完成。

As the guarantee of the three gorges ship lock series conversion and fold beam door put down the safe operation,The Yangtze river three gorges navigation administration in the conversion operation series before timely issued a notice,Reasonable arrangement in stage during the period of dispatching work.In the mode of operation in the process of conversion,Technical personnel on the lock chamber of the initial water level have been adjusted,To ensure that the three gorges lock series conversion to successful completion of the work.
