中断的

Taking out a spinlock in an interrupt handler is a legitimate thing to do; that is one of the reasons that spinlock operations do not sleep.

在中断服务函数中获得一个自旋锁完全合理；这也是为什么自旋锁操作不能休眠的原因之一。

While the interrupt handler is spinning, the noninterrupt code will not be able to run to release the lock.

当中断服务函数进入自旋时，以非打断方式运行的代码将无法释放该锁。

For example, when you press a key on your keyboard, the signal is sent to the keyboard interrupt handler, which tells the CPU what it is and passes it on to the operating system.

例如，当你在键盘上按一个键的时候，信号就被发送到键盘中断处理程序，后者告诉CPU 这个信号是什么并把它传给操作系统。

Usually a thread waits on a semaphore that is signaled asynchronously by an interrupt handler.

通常情况下线程等待一个由中断服务发出异步信号的信号量。

It is a global masking process for any interrupt of level higher than n.

对于比n更高的任何中断级来说，这是一个总的屏蔽处理。

Differences between interrupt level trigger and edge trigger modes are realized.

Use a semaphore to synchronize the interrupt handlers with the pending requests.

使用 semaphore 来同步化迫近要求的中断处理者。

Some use of assembly language software, the use of methods to detect interrupt the user requests the key information, according to the lift operation to the appropriate floor, a photoelectric sensor-level changes to the SCM count to determine the number of floors, and sent to the digital display.

软件部分使用机械设计汇编语言，利用中断方式来检测用户请求的按键信息，根据电梯运行到相应楼层时，光电传感器产生电平变化，送到单片机计数来确定楼层数，并送到数码管进行显示。

More modern hardware often has one or more interrupt status registers that latch the interrupt requests; well written edge-driven interrupt software often checks such registers to ensure events are not missed.

写得好的沿驱动中断软件通常检查这些寄存器以确保不会丢失事件。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
