In the automatic sprinkler system,alarm valve is acritical component,and its role to three factors:connect or disconnect the water supply,the output600X Hydraulic Electric Control Valve alarm signal and the prevention of water pumped back into the water supply source,and through the alarm valve can be installed on the system of water supply and alarm device for testing.

在自己主动喷水灭火系统中，报警阀是至关重要的组件，其作用有三：接通或切断水源、输出报警信号和防止水流倒回供水源，和路程经过过程报警阀可以对系统的供水装配和报警装配进行查验。

Besides, there are some special system administrators responsible for the run and maintenance of the whole system.

此外还需要有专门的系统管理员来完成系统的运行维护工作。

Chapter two dissertates the component and its configuration of the on-line supervisory control of hydraulic system of walking beam, including the aim, the content and the design principle of this kind of system is also discussed here, and then it introduces the application on network and PLC on-line supervisory control system for this project, including the comparability and affirmance of this system, and also introduces the actual component of this system.

接着论述了基于网络和PLC的监控系统组成在本改造项目中的应用，主要内容有：步进梁液压监控系统方案的比较，方案的确定，实际的在线监控系统的组成以及主要配置等。

Although the quality and quantity of mobile anti-aircraft gun systems remains unknown, there is no indication of any mobile surface-to-air missile systems other than man-portable systems such as the SA-7 and SA-14 or SA-16 entering the inventory to augment North Korea's static air defense umbrella.

虽然质量和数量的移动高射炮系统仍然未知，目前并无迹象显示有任何的移动型防空导弹的系统以外的其他单兵携带系统，如的SA - 7和SA - 14或SA服务-16进入库存，以加强北朝鲜的静态防空保护伞。

The apriori and aposteriori H〓-optimal filtering question can be solved directly. L〓 Apriori and aposteriori filtering with an H〓 error bound can be solved by semidefinite programming. Robust H〓 apriori filtering and robust apriori L〓 filtering in discrete-time system are subject to a nonconvex constraint.

对这些滤波问题解法的改进同连续系统下的情况基本类似，对确定性系统的H〓验前滤波和验后滤波，本文解法可直接得出最优滤波问题的解；对H〓约束下的L〓验前滤波及验后滤波，其解可归结为一凸优化问题；但不确定性系统H〓验前滤波和鲁棒L〓验前滤波的LMI解法中有了非凸约束，因此要用迭代法求解。

The construction of argot has his lexical system and syntactic system, average person looks without Zhang Ke abide, understand hard.

隐语的构造有自己的词汇系统和语法系统，一般人看来无章可循，难以理解。

The satellite navigation system has been an indispensable assistant tool for the car drivers due to its popular applications and flourishing development. There are more and more carmakers to provide the navigation systems as a standard device for a new car.

近年来随著卫星导航系统的蓬勃发展，其在日常生活中的应用日见广泛，且车用导航系统更对部份民众而言，亦已成为不可或缺的行车辅助工具，因此也有愈来愈多的汽车制造商已将行车导航系统列为新车出厂时的标准配备。

The results show that hydraulic pipe diameter has great influence on dynamic response of the directly-driven hydraulic system,and pump damping obviously affects output pressure and velocity of the hydraulic system.

研究结果表明：液压系统的管路直径对系统的动态响应有较大的影响，泵的阻尼对液压系统的输出压力及输出速度影响很大。

A world with a dynamic balance of power that is then intertwined with an outstanding new Casus Belli system where nations have definite objectives and foreign policies… which in turn blends perfectly with the Spheres of Influence concept.

有然后与国家有明确的目的和外交政策的一个杰出的新宣战系统系统一起纠缠的一个动态的势力均衡的一个世界…哪一个依次完全地以影响力观念的球体混合。

Based on normal automatic rifle with shooter standing firing without support andprone firing with support, the dynamics characteristics of man—weapon system werestudied, the physical and mathematical models of the above two firing gestures wereestablished.

本文以常规结构自动步枪的立姿无依托抵肩射击和卧姿有依托抵肩射击系统为研究对象，对人枪系统的动力学特性进行了系统的分析，建立了两种射击状态的物理模型和数学模型。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
