The locking block mechanism clamping better than now screw clamp mechanism.
利用挟持块锁固较目前现行锁固方式更为紧固。
With locking, if one thread attempts to acquire a lock that is already held by another thread, the thread will block until the lock becomes available.
使用锁定，如果一个线程试图获取其他线程已经具有的锁定，那么该线程将被阻塞，直到该锁定可用。
If pessimistic session locking is used, it should generally only be used to block other users from updating; it should not block reads of the locked data.
如果使用悲观会话锁定，它通常只用于阻止其他用户进行更新，而不是阻止对锁定数据的读取。
File object locking is not available, but the modified block storage technique can be introduced here the way we did in this article to maintain data consistency.
文件对象锁定不可用，但已修改的块存储技术可在此引入，按照本文介绍的方式保持数据一致性。
When scanning an MDC table, block locking could be deferred for an index scan.
当扫描一个mdc表时，对于索引扫描，块锁可以推迟。
For MDC tables, the selection of BLOCKINSERT may improve the performance of INSERT operations by locking at the block level and avoiding row locks for INSERT operations.
对于mdc表，选择BLOCKINSERT可以提高INSERT操作的性能，因为使用的是块级的锁，避免了为INSERT操作使用行锁。
This addresses the data race, but has further costs for concurrency, since locking the entire list while iterating could block other threads from accessing the list for a long time.
这样做虽然解决了数据争用问题，但是在并发性方面付出了更多的代价，因为在迭代期间锁住整个list会阻塞其他线程，使它们在很长一段时间内不能访问这个列表。
Unlike locking, volatile operations will never block, so volatiles offer some scalability advantages over locking in the cases where they can be used safely.
volatile操作不会像锁一样造成阻塞，因此，在能够安全使用volatile的情况下，volatile可以提供一些优于锁的可伸缩特性。
However, block locking was not be deferred for table scans.
然而，对于表扫描，块锁不会推迟。
By forcing a timing reacquire, the front end block resets and "hunts" for a video signal, thus ensuring the speedy locking to a new video source.
通过强制再获取时序，前端模块复位并搜索视频信号，从而确保迅速锁定新的视频源。
Since persistent storage is a block device, locking is controlled by the host it is assigned to (Figure 2).
因为持久性存储是一种块设备，锁定是由它指定的主机来控制的(图2)。
The hydraulic circuit and block the upper limit locking mechanism is provided with a compressor, good safety performance.
压机设有液压回路和滑块上限位锁紧机构，安全性能好。
Pursuing protectionism is like locking oneself in a dark room. While wind and rain may be kept outside, that dark room will also block light and air.
搞保护主义如同把自己关进黑屋子，看似躲过了风吹雨打，但也隔绝了阳光和空气。
Meanwhile, the wedge-shaped design of the fixture block can play the role of self-locking, and thus causing the moving and static contacts to be steadily contacted.
同时，卡块的楔形设计能起到自锁的作用，使动静触头能够稳定接触。
The locking catch block can conveniently assemble a plurality of wood floor blocks together, the assembly is convenient and simple, and the wood floor is not easy to deform after assembling.
它可以方便地将多个木地板块组装在一起，安装方便简单，安装后，木地板不易变形。
