When multiple threads ask for the same lock at the same time, one wins and acquires the lock, and the others block.
在多个线程同时请求同一个锁时，会有一个线程获胜并得到锁，而其他线程被阻塞。
For optimizing existing applications using client optimization, you can generate multiple capture files to lock captured information during incremental capture.
要使用客户端优化优化现有应用程序，可以在递增式捕获过程中生成多个捕获文件来锁定捕获的信息。
The purpose of a lock is to protect a mutable resource, or stated another way to protect potentially multiple users of that mutable resource from accessing a corrupt version of the resource.
锁的目的是为了保护可变资源，或者换句话说，是为了避免可变资源的多个潜在用户访问资源已被破坏的版本。
If multiple threads attempt to lock a semaphore after the initial call above, they block and their requests are queued until the pthread_mutex_unlock call is performed.
如果多个线程在完成上面的初始调用后尝试锁定信号量，则这些线程会被阻塞，它们的请求进入队列，直到执行pthread _ mutex_unlock调用。
This means that multiple threads can access different portions of the Map simultaneously, without contending for the single collection-wide lock.
这意味着多个线程可以同时地访问一个Map的不同部分，而不必争用单个的集合范围的锁。
It makes room for multiple implementations of lock, which may have different scheduling algorithms, performance characteristics, or locking semantics.
这就为Lock的多种实现留下了空间，各种实现可能有不同的调度算法、性能特性或者锁定语义。
If multiple arrows show a circular lock-request pattern — threads prevent each other from running because they are waiting for each other to release a lock — then you have a deadlock.
如果多个箭头显示一个环形的锁请求模式—由于它们正在相互等候其它线程释放锁，所以线程彼此阻止运行—结果就形成了一个死锁。
Otherwise, you can use the "recursive" mutex type, which allows the holder of the lock to lock the same mutex multiple times.
另外，您还可以使用“递归”类型的互斥量，这种互斥量允许对同一个互斥量锁定多次。
A lock-bound application is one in which multiple threads are fighting over the same locks.
在一个锁关键型应用程序中，多个线程在相同的锁上争用。
You might recall the graphs from last month's column showing how throughput can drop dramatically once multiple threads contend for a built-in monitor lock using synchronization.
您可以回想上月专栏中的图，该图显示了一旦多个线程使用同步竞争一个内置监视器，吞吐量将如何大幅度下降。
There are multiple safe protectors: Overweight device, chain fracture device, trailing arm lock protect, device of the lock when it rised.
设有多重安全保护装置：超重装置，断链装置，托臂自锁保护，上升过程中的自锁装置。
Each center is guarded by multiple security procedures, including biometric identification, key card access, elevator lock outs and human verification.
每个中心采用多种安全手段以保证安全，包括生物识别、门禁卡、电梯锁和人工检查。
There are multiple safe protectors: Overweight device, chain fracture device, device of the lock when it rised, there is a lock that stops the device on each post.
设有多重安全保护装置：超重装置，断链装置，上升过程中的自锁装置，每个立柱上均有锁止装置。
Likewise, the lockreqs (lock requests) may have rolled over multiple times.
同样，lockreqs(所请求)已经翻滚很多倍。
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。
This method supports multiple granularity lock, automatic lock and automatic lock escalation.
该方法支持多粒度锁、自动加锁特性和自动锁粒度升级特性。
The system works with the 79 contactless RFID electronic lock, which offers multiple locking options and is tamper-resistant.
系统可对79个免接触RFID电子锁起到控制作用，从而支持多种所选项也能防止被篡改。
The design of the injection mold of multiple points, plates and molded surfaces is simplified by using lock catch facility, joined tie-bar structure and decreasing the guide-pin amount.
应用锁扣装置、组合拉杆结构，减少导柱数量，简化了多点多板多分型面注塑模具的设计。
A thread is counted only once, even if the lock allows recursion and the thread has entered read mode multiple times.
即使锁定允许递归并且线程已进入读取模式多次，也只对每个线程计数一次。
Described are the main technical parameters of 3 types of tight-lock draft gears for multiple units in Europe and Japan, which are going to be imported by the Railway in our country.
