定时的

In case of some special type of systems, when emergency strikes or when some irrecoverable error occurs, embedded systems implement watchdog timers which just reset the system.

如果在某些特殊类型的系统，当紧急情况或当一些无法挽回的错误发生，嵌入式系统的实施看门狗定时器刚刚重置系统

Development of OA kneepad: Under the principle of＂treating cold syndrome with hot-natured drugs＂ and ＂treating blood stasis syndrome with promoting blood circulation and removing blood stasis drugs＂,PIC16F630 SCM was served as the core and mainly composed of four parts including the boost circuit, the output, single-chip microcomputer control, as well as electric soft membrane.

OA护膝的研制：根据中医"寒者热之"、"瘀者通之"的治则，以PIC16F630 单片机为核心，电路主要由升压、输出、单片机控制以及电热软膜4 部分组成，通过键盘设定单片机产生不同幅度和频率的动态变频疏密波进行治疗，30min 后单片机内部定时器中断，自动关机。

Therefore, in using the computer, attention should be given by eye care health and head of science, such as: focus should not be too long eyes, may from time to time towards the blue sky, green plants, distant scenery, and consciously increase in blink frequency, eat more dependent The purpose of eye care food such as milk, carrots, liver, matrimony vine, dark green vegetables, may be appropriate to use the eye drops to ease eyestrain.

因此，在使用电脑时，应注意用眼卫生及科学护目，如：不应过久集中用眼，可定时远眺蓝天、绿色植物、远方的景物，自觉的增加眨眼次数，多吃养睛护目的食物，如牛奶，胡萝卜，猪肝，枸杞，深绿色蔬菜，可适当使用一些能缓解眼睛疲劳的眼药水。

As required by the working features of monostable flip flops, the design idea of monostable flip flops with RC circuit as the timer unit is explained by using the transient phenomenon of signal changing resulted from the differential circuit or from "the static race hazard of signal", and by linking the storage principle of signal feedback.

根据单稳态触发器工作特点的要求，以RC电路为定时单元，利用微分电路及"信号静态竞争冒险"等信号瞬变现象，并结合信号反馈存贮的原理，阐明单稳态触发器的设计思想。

The Analysis shows that the bigger the variation coefficient of dependent variable,the bigger the mean square error of regression equation when the multiple correlation coefficient is definite.

分析表明，复相关系数一定时，倚变量的变差系数越大，回归方程的均方误差就越大；回归分析时，应对回归方程的误差进行分析。
