guarded section meaning in Chinese
保护区段
保护区域
Examples
- Structured exception handling also lets you easily provide cleanup statements that you can be sure will always execute no matter how control leaves a guarded section of code
结构异常处理还让你轻易的提供清除声明，这样你可以确信：它将永远执行无论控制余下一个代码的防护区域。 - Closely integrated with the compiler ' s code generator , structured exception handling lets you easily place a guard on sections of your code and invoke exception handlers when something goes wrong in the guarded section
用编译器的编码发生器紧密结合，结构异常处理使你轻易的在你的代码区域上放置一个防护装置，并且当被防护的区域内出现错误的时候调用异常处理器。 - At present , the most of vtr which are used in watch - control occasion for speciality are short of a uniform control - check - alarm system , which brings on the discommodiousness of operation and the user can not know the time of occurring a fault , which reduces the reliability of the watch - control system . therefor , at first , i carefully analyze the servo theory of the vtr which had been produced by chmavc with k mechanism to find out the work rule of the control signal ; second , take out some right control signal ; then for dealing with the problem of vtr in use for watch - control , i choose some right components to design the uniform control system for many special vtr with protel software . it mainly includes the following functions : operation functions of all vtr ( for example : power , play , ff , rew , stop , rec , eject , fwd , rwd , sp , lp ) was controlled by line at the same time ; in , the process of recording , when the tape walks to the end or stops by itself , the system gives an alarm and shows the number of the wrong vtr ; in the process of recording , the system gives an alarm and shows the number of the wrong vtr when the video signal from vidicon is losed ; the system controls all vtr to record on the non - working time when there is something wrong in the guarding section ; the system controls the video from vtr to switch to right monitor
目前，用在监控场合的业务用录像机普遍缺乏一个统一的控制及检测报警系统，这就导致了操作的不方便和出现了故障用户不知道，降低了监控系统的可靠性，为此，我首先对华录松下生产的k机芯的录像机伺服原理进行仔细分析，找出各个伺服控制信号的控制变化规律；然后从中选出合适的控制信号；针对目前录像机在实际监控使用过程中存在的问题，选用合适的元器件；运用protel绘图软件，设计了这个多台业务用录像机的统一控制系统，她主要包括以下功能：录像机操作功能(如power play ff rew stop rec eject及正寻反寻带速设定等)的统一线控控制功能；磁带在记录过程中，磁带到头和磁带自己“偷停”的报警，并要能显示出具体是哪一台录像机；在记录状态下，摄像头输入信号丢失报警，并要能显示出具体是哪一台录像机；在休息或其他不需要记录时，一旦警戒区有情况，则控制所有机器自动进入录像状态的功能；从录像机输出的监控图像信号对监视器的切换功能。
