延时阀

The alarm valve should be installed vertically. When there is a fire in the protected area, temperature rises up, pressed water jet from sprayer, and the alarm valve is initiated to jet water onto fire. After 5-20 seconds, the delayer will sent out alarming signal to ring the bell for fire extinguishing.

当保护区某处发生火灾时，环境温度升高，闭式喷头的维护敏感元件破裂，压力水从喷孔口喷出并自动启动报警阀将水直接喷向火灾发生区域，延迟器延时5-20秒后发出报警信号，带动警铃以达到报警、灭火的目的。

The feasibility,effectiveness and limitation of four improvement measures are studied:raise protection settings or prolong protection delay;apply inverse time limit ;use additional criterion to distinguish valve fault from AC system fault;and adjust 100 Hz protection configuration principle.

为减小交流系统故障期间直流100Hz保护动作的概率，利用PSCAD/EMTDC仿真分析软件，就阀故障和交流系统故障时直流线路50Hz/100Hz电流特性进行了分析，研究了提高保护定值或延长保护动作延时、采用反时限特性、利用附加判据区分交流故障和阀故障、调整直流100Hz保护配置原则4种措施的可行性、使用后的效果及局限性。

Its basic principle is to monitor the arc light automatically by the photosensors; the photoelectric signal is analysed and processed automatically by the microprocessor, then it drives the liquid crystal light valve to turn from a "clear state" into a "dark" protective state rapidly . Meanwhile , when the arc light disappears, the system makes the liquid crystal light valve resumed the bright attitude by auto-delay,and microprocessor adjusts eye protection circuit intelligently to reduce the consumption in the maximal degree, which make the working time achieved one or two years by ordinary button cell cooperates with photocells .

其基本原理是由光敏器件自动监测弧光，光电信号经微处理器自动分析处理，快速驱动液晶光阀由透明的亮态迅速变为保护的暗态，当弧光消失时自动延时使液晶光阀恢复亮态；并且微处理器智能调整护目镜电路的工作姿态，最大程度降低功耗，使得普通的扣式电池配合光电池便可以工作一至两年。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
