报警的

At last using ODTR (Optical Time Domain Reflectometer) to measure the attenuation of the Rayleigh intensity at the starting point of fiber, the disturbance and breakage of pipeline is detected, and the location where the optical attenuation occurred is located.

在入射端利用光时域反射技术(ODTR， Optical Time Domain Reflectometer)测量瑞利散射光的损耗变化，检测管道受到的扰动破坏和实现扰动点的定位，进而在破坏的初期即可实现报警。

Then the types of upper sensors are determined. The CMOS chip AT89C2051 is used in this system because there is only a small quantity of program to be stored. This system uses wireless transmission module D21DL to form the network of wireless transmission. In this way, such disadvantages as low removability and expansibility and longtime construction are avoided. Digital filtering method is applied to improve anti-jamming performance.

由于程序存储量较少，现场的CPU选用ATMEL公司的低档型芯片AT89C2051；为了避免采用有线数据传输导致的系统可移动性差、系统扩充性能差和系统布置线缆繁琐、施工周期长等缺点，本系统采用了无线数据传输模块D21DL构成系统无线网络传输；同时设计了包括电源电路、显示电路、存储电路和报警电路等构成系统的所有电路。

Not only can effectively control the squirrel-cage three-phase asynchronous motor starting current, the current slowdown of the motor and the impact of power grids, and the structure is simple, reliable operation and lower costs for promotion, but also in the process of starting and running current detection, Voltage parameters, the abnormal processing, display and alarm, to achieve the comprehensive protection of the motor.

不仅能有效控制鼠笼式三相异步电动机起动电流，减缓电流对电动机和电网的冲击，且结构简单，运行可靠，成本较低，适合推广，还能在起动和运行过程检测电流、电压参数，对异常情况进行处理、显示及报警，实现对电动机的综合保护。就是以上的了，电气专业英语好的帮下忙，万分感谢

This system is designed to apply the technology of SCM control, taking the signalchip 8051 as the core ,to control the water level of the water tank of 800 stere, and achieved the warning system and switching manually i order to conform to the demand of working system control, this performance system is operated convenient.

摘要摘要：本单片机系统设计的目的是应用单片机控制技术，以8051单片机为核心控制某电厂的800立方米的水箱水位控制系统，并实现了报警和手动、自动切换功能该系统操作方便、性能良好，比较符合电厂生产用水系统控制的需要。

However, the current DCS just rests on conventional inspection and alarm with still lots of functions lying fallow, which leads to waste of hardware resources.

然而，目前的DCS系统只停留在常规的检测和报警，尚有大量的功能没有挖掘出来，造成硬件资源的浪费。

Intrusion traceback is an important technology in network security aspect,,which is aiming at tracing the real source of attacking, providing precise information for alarm and supplying reliable proof for post-crime testification and improving network system's security.

入侵跟踪是计算机网络安全领域的一个重要技术，其目的是跟踪攻击的真正来源，为报警提供精确的信息，以及事后的犯罪举证和修补网络系统安全漏洞提供可靠依据。

And what we do Computer lab fire prevention burglary-resisting system to answer require but make this, computer lab fire prevention burglary-resisting system adopt the infrared sensor, Temperature sensor, gas detector have lens , spend system able to programmer simulation circuit and picture transmit and implement and control 2 4 hours to computer lab correctly with subminiature device, Find unusual situation auto alarm , play a firing prevention and guard against theft role really , can make computer system relatively safe in one, In the reliable environment, operate steadily for a long time, and lengthen service life to the best of one's ability.

而我们讨论的机房安全措施正是应此要求而做的，机房安全措施统通过红外传感器，温度传感器，气体探测器还有摄像头，利用系统可编程模拟电路ispPC20以及用CCD超小型器件对图像传输对机房实施二四小时监控，发现异常情况自动报警，真正起到安全防范的作用，能够使计算机系统在一个相对安全，可靠的环境里，长时间稳定地运转，并尽可能延长使用寿命。

It has the same style with LTHS100E, however, its functions were improved based on the old style; at present, LTHS100B applies imported wind pump assembly which has twice theme ---absorb and blow (increase parts on positive pressure air, strengthen the pressure that can deliver the unmelted flux directly into little hopper); the height of material absorbing and delivering can reach as high as 5 meters, and its level distance is around 12 meters, and the capacity of flux depends is 80KG; the suspended function also can be tailored according to customers' requirements; the weight of 100B is 130KG, its outer dimension is 450*800*1100mm. It has the advantages of small-volume, light-weight, beautiful-outer-appearance, unnecessary of air-compression, and can be ground-mounted or suspended; it is also easy to be operated, with switching on button, it can be operated. Furthermore, it is controlled by infrared ray. It has alarming lights.

该机与LTHS100E机形相同，但其主要特点：在LTHS100E的基础上精心整改了其功能，现LTHS100B是采用进口风泵总成为基础，吸、吹二次全部为主题（在正压气上增加了部件，增强了压力把吸收回来没有融化的焊剂直接推送到前方机头的小料斗内，）焊剂的吸、送料其高度不得超过5米，水平距离在12米左右，焊剂容量为80KG，可悬挂也可根据用户需要为用户量身订制，自重为120KG，外型尺寸为：450*800*1100mm，本机具有体积小，重量轻，外型美观，不需要具备压缩空气，可落地、可悬挂灵活，其操作简便为一线通即可，红外线控制，上方有警示灯显示，当焊剂不足时就会报警。

Product research and development company has strong strength and control in the production process has a strict control system, together with the products of advanced electronic components, therefore, anti-theft alarm Avis products in the market have a strong competitive force.

公司在产品研制开发方面有很强的实力，在生产过程控制方面拥有一套严格的控制体系，加上产品都采用先进的电子部件，因此，安飞防盗报警产品在市场上有很强的竞争力。

The main function of the electronic burglarproof system is voice and light burglarproof, mute burglarproof

另外这类型的报警系统容易受外界的噪声干扰，产生误报，对周围的环境产生严重的噪声干扰。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
