A lock can be acquired in one of two ways, recursively or non-recursively.
可以通过两种方式(递归地或非递归地)的其中一种来请求锁。
So for example, instead of concurrent linked lists, we use dual concurrent lock circular arrays, so we have the benefits of non blocking concurrency without object creation.
因此，相对于并发链表，我们采用了二重并发锁循环数组（dual concurrent lock circular arrays），这样无需创建对象就能享受到非阻塞并发带来的好处。
This routine takes in two arguments, the second being the absolute value of time by which, if the lock could not be acquired, the routine returns with a non-zero status.
这个例程有两个参数，第二个参数是绝对时间值。如果在到达这个时间时还无法获得锁，例程会返回且状态码非零。
But the simplest way to help the black family would be to lock up fewer black men for non-violent offences.
但帮助黑人家庭最简单的办法是，若黑人男性涉非暴力犯罪，那就少判他们入狱。
No locks will be included; this kind of lock-free, concurrent data structure is also referred to as a non-blocking data structure.
这个堆栈没有锁；这种无锁的并发数据结构也称为非阻塞数据结构。
The lock function must immediately check and return (non-blocking).
lock函数必须立即进行检查并返回(非阻塞方式)。
And you should never unlock a mutex that you don't hold a lock for (otherwise, the pthread_mutex_unlock call will fail with a non-zero EPERM return value).
并且绝对不要对您未保持锁的互斥对象进行解锁操作(否则，pthread _ mutex_unlock调用将失败并带一个非零的eperm返回值)。
That's it – blocking occurs not because multiple sessions are trying to update the same data, but because of non-optimized query that needs to process/acquire lock on the data it does not really need.
所以阻塞的发生并不是因为同时有多个会议尝试去更新相同的数据，而是因为没有经过优化的查询申请了锁，但读取到的数据往往是不必要的数据。
Please lock the non-slip handle when you push the wheelchair. When you need adjust the height of the back, please unlock the non-slip handle.
推出轮椅请锁紧防滑手柄；推出轮椅后，需要调节轮椅椅背高度时，请注意松开防滑手柄；推进床体后，调节椅背高度时，请注意松开防滑手柄。
A non locker code got a request to reserve the lock for making global updates.
非锁定程序代码收到一个为全局更新保留锁定的请求。
The fracture of the pump shaft is mainly caused by large size non metallic inclusions and point welding between the lock nut and the pump shaft.
结果表明，大尺寸的非金属夹杂和背帽外缘的点焊是引起泵轴过早断裂的主要原因。
The main force of the recent strong retail investors may also want to help Lock, non-firm elements changing hands.
