A 2-d numerical model of wave motion in lockapproach channel is described, which is soluted by using the method of resultants of 2-d numerical model of unsteady flow and 1-d numerical model.
提出船闸引航道内水面波动的二维数学模型，采用二维非恒定流数学模型和船闸灌泄水一维数学模型联解。

Even with a few failed CAS operations, this approach is still likely to be faster than being rescheduled because of lock contention.
即使有少量失败的CAS操作，这种方法仍然会比由于锁争用造成的重新调度快得多。

Another approach is to use POSIX record locks, implemented through FCNTL (2) as a discretionary lock.
