With electricity - liquid integration technology , it is stable and reliable in performance . with the jointed arm , it is controlled with flexibility . it can be self - locked in any height with safe operation 该机采用了电- -液集成控制技术，性能稳定可靠；使用摇杆操作系统，使用方便灵活；可在任何高度自动锁定，使用安全。
A single server process that accepts client requests one at a time , processes that request to completion , and then gets the next request , in some sense automatically locks all the objects inside it . such a simple design is immune to many nasty locking problems 一个单独的服务器进程每次只接受一个客户机请求，然后处理该请求，直到完成该请求为止，而后再获得下一个请求，从某种意义上讲，进程内部的所有对象是被自动锁定的；这种简单的设计可以避免很多危险的加锁问题。
