This is when a context switch actually occurs: If _Running == _RunQueue, that means no context switch has been requested and _Epilog simply restores the registers saved by _Epilog.

当_SysLevel 变为负数时，就必须切换到进程堆栈上去，这时环境切换才真正发生：如果 _Running == _RunQueue ，就意味着没有切换运行环境的必要，_Epilog 就简单的恢复个寄存器的内容（通过指针_RunQueue ）。

Optical switch is the key element of all optical network. MEMS optical switch arrays, which can achieve small insertion loss, low cross talk and large switching contrast, are going to be the key considerations in the optical cross connectors and optical add/drop multiplexers for optical networking.

光开关是全光交换的关键器件，MEMS光开关由于具有潜在插入损耗和串扰低、消光比高等诸多优点而成为光网络中光交叉连接和光分插复用器的主流器件。

Maths emulates a result to make clear, apply slant buy scale guides the switch number that brings certain engine switch route to be able to reduce quantity of miss the target and course apparently to accuse engine.

数学仿真结果表明，运用偏置比例导引确定的发动机开关线能够明显地减小脱靶量和轨控发动机的开关次数。

Through controlling SenseFET, PWM the function compositive in small enclose inside, these power switch can save a space, the intermittent job mode with advanced at the same time have the aid of will assure low switch loss, achieve a system to bide one's time thereby power comsumption under 1 tile.

经由过程将SenseFET、PWM节制性能集成在小封装内，这些功率开关能够节省空间，同时借助前进前辈的间罢工作模式来包管低开关损耗，从而达到系统待机功耗低于1瓦。

This article introduced the manipulator, it outputs four groups by PLC to actuate the abscissa axis, the z-axis, the chassis rotation, hand-rotating motor separately, and controls the manipulator abscissa axis and the z-axis pint pointing, the micro switch bequeaths the position signal to the PLC main engine; The electrical machinery drives the hand fingernail and the chassis revolve; The solenoid valve controls air valve the switch to control the manipulator hand fingernail to gather, then realizes the manipulator proper motion function.

本文介绍的机械手是由PLC输出四路来分别驱动横轴、竖轴、底盘转动、手转动电机，控制机械手横轴和竖轴的精确定位，微动开关将位置信号传给PLC主机；电机拖动手爪和底盘旋转；电磁阀控制气阀的开关来控制机械手手爪的张合，从而实现机械手精确运动的功能。

Intelligence power: the driver steps down the accelerator pedal to intelligence power switch and continue to step it down with bigger force when the vehicle needs accelerating and overpassing other vehicles, the accelerator pedal will press down the intelligence switch when the accelerator exceeds the normal full accelerated position; now the engine will emit higher power than rated power in a short time, so the vehicle will get a stronger acceleration.

智能动力：当车辆需要加速超车时，司机踩下油门踏板至智能动力开关，并继续以较大的力往下踩时，油门超越正常的全油门位置，将智能开关压下，此时发动机会短时地发出比标定功率更高的功率，车辆因而获得更加强劲的加速性。
