对互斥对象解锁会立即发生，但等待条件mycond通常是一个阻塞操作，这意味着线程将睡眠，在它苏醒之前不会消耗CPU周期。
Unlocking the mutex happens immediately, but waiting on the condition mycond is normally a blocking operation, meaning that our thread will go to sleep, consuming no CPU cycles until it is woken up.
在经济繁荣之前，通常有一个低利率的过程，这也是经济向繁荣周期转化的一个先决条件。

他们探究了“周期性”和“结构性”失业之间的渐变过程和两者产生、转换的条件。

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 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).

Using fixed point theorems, in this paper we give sufficient conditions of the existence of bounded mild pseudo almost periodic solution for some semilinear differential equations.
在经济繁荣之前，通常有一个低利率的过程，这也是经济向繁荣周期转化的一个先决条件。
Prior to boom period, usually there is a period of low interest rates, which is the precondition for the economy to cycle to boom.
上面的方法不能用于负载特性分析，原因在于不能确定周期性的边界条件。
However, this approach cannot be used for analysis of load characteristics because it proves impossible to specify periodic boundary conditions.
