This will only happen on the first iteration of the loop, saving valuable execution time on each subsequent iteration.
这样，它只在循环第一个迭代时执行，从而在以后每次迭代时节省了宝贵的时间。
You can now call this method and interrupt execution at any point of the loop, capturing the state of the program.
现在，可以调用这个方法并在循环的任意位置中断执行，这会捕获程序的状态。
Then, break the execution and find the assembly code representing the infinite loop.
然后，中断执行并找到表示该无限循环的汇编代码。
This completes the execution loop with analysis and process adaptation techniques feeding back to the modeling step.
这样就完成了将分析和流程调整技术反馈到建模步骤的执行循环。
But, because the thread at priority 4 executes first, it should have a slightly larger share of the five-second execution interval and print out a higher loop count.
但是由于首先执行优先级为4的线程，因此在五秒钟的执行时间间隔中，它分得的时间稍多一些并且打印的循环计数也稍大一些。
In the previous picture, you can recognize some logical constructs that help with structuring the flow with conditional execution (the Switch activity) and with cycles (the Loop).
在前面的图中，您可以辨认出一些逻辑结构，这些结构可以使用有条件执行(Switch活动)和周期(Loop)帮助构建此流。
In the first example, the results of List.size could become invalid during the execution of the loop, because another thread could delete items from the list.
在第一个例子中，List .size的结果在循环的执行期间可能会变得无效，因为另一个线程可以从这个列表中删除条目。
The Events tree lists all test execution events, such as the script start and end, loop, invocation, message, or verdict.
这个Events树列出了所有的测试执行事件，比如脚本起始和终结、循环、调用、通知，或者结果。
Here's what happens at execution time for the first leg of the nested loop join.
以下是在执行嵌套循环联接的第一步时将发生的操作。
You create the necessary network listening sockets, register the events to be called during execution, and then start the main event loop with the libev handling the rest of the process.
创建所需的网络监听套接字，注册在执行期间要调用的事件，然后启动主事件循环，让libev处理过程的其余部分。
It can be used to hold a loop count that can be decremented during execution of Branch instructions.
它可用于保存可以在执行Branch指令期间递减的循环计数。
Once the execution is out of the loop, let's assume that the instance state is one of two values.
执行跳出循环后，我们假设实例状态是下面两个值之一。
The feedback loop is the amount of time between making a change in code and seeing the results in the execution of your application on the screen.
反馈周期是从改变代码到在屏幕上看到执行应用程序的结果所用的时间。
And, every execution of the inner loop will generate a query that looks like so.
而且，每一个内部循环的执行将产生一个查询，看起来像这样。
This execution block was then placed within a for loop and the sum of the execution times was recorded as the total execution time for a given test scenario.
然后将该执行块放在一个for循环中，并且将执行时间的总和作为给定测试方案的总执行时间记录下来。
At this point, the break statement causes program execution to break out of the while loop, skipping the else clause.
此时，break语句导致程序执行中断while循环，跳转到else子句。
An unhandled exception was caught in the application driver execution loop.
在应用程序驱动程序执行循环中，发现未处理的异常错误。
The test of a conditional expression occurs before the execution of the loop.
条件表达式的测试发生在执行循环之前。
Software pipelining is a loop scheduling technique which extracts instruction level parallelism by overlapping the execution of several consecutive iterations.
软件流水是一种开发循环程序指令级并行性的技术，它通过并行执行连续的多个迭代来加快循环的执行速度。
A loop that has no exit and whose execution can be interrupted only by intervention from outside the computer program in which the loop is included.
没有出口的一种循环，只能用包含该循环的计算机程序之外的干预来中断。
If you've already tried the loop optimization techniques presented in Chapter 4 but haven't been able to reduce the execution time enough, then timers are your next optimization step.
如果你已经尝试了第四章介绍的循环优化技术，但还是不能缩减足够的运行时间，那么定时器就是你的下一个优化步骤。
