The main advantage of this concept is that the consecutive controller is able to control disturbances of humidifying arrangement directly, because the dew point measurement of the humidifier has got a very short response time compared with the quite longer response time of the furnace dew point. This is caused by bigger time delays of the measurement and the delay time of the process gas to come into the furnace.Analysis station for CO/CO2, H2 and O2ppm monitoring, extracting method will be multiplexed sampling An analysis station designed as a complete functional unit will be used for monitoring the composition of the atmosphere in the Furnace.The analysis station will be a single-cabinet unit complete with analyzers, pumps, solenoid valves and control unit. In normal operation, the sample gas switchover system will switch cyclically between the different sample gases. The system can also be switched to nitrogen for purging or to a calibration gas; this is not part of the normal cycle.The sample waste gas will be fed from the sampling probe on the furnace (with filter) to the analyser or sample gas treatment system through a sample gas line routed downwards. Sample gas from each sample gas point will be extracted by the main sample gas pump to the analyser station. The sample gas 'in measurement' will be switched to the measurement line from where an additional pump pumps it to the analysers. The sample gas lines will be made from acid-resistant plastic.The multiplexing analysis system has following probes:For CO/CO2 the system in an actual mode can be calibrated automatically every day using an in-built comparison probe. The calibration time is triggered using an internal period value, which can be changed manually. During calibration time no measurement values are available. A particular feature will be to switch from multiplexing measuring mode to single mode, where a certain probe gas inlet can be measured continuously and vice versa.这一进程所提供的气体，搅拌站在预热时将用换热器。

4.求一篇关于电气自动化的中英文的科技文献的,大约3000字左右
摘要：本文主要介绍了近年来电气自动化技术的发展，以及应用的概况。
电气自动化技术尽管已经广泛应用与我国国民生产的各个部门和领域，但它仍需要不断革新，不断发展。关键词：电气自动化；发展；应用一、发展概况 伴随着我国的电力电子技术、微电子技术的飞速发展，电气自动化的概念已经走出了工厂，并在交通、农业、建筑、办公场所等方面得到了广泛的应用，电气自动化技术作为从电气工程技术发展出来的并与电子与信息技术紧密结合起来的一门电气工程应用技术学科，历经了近一个世纪的发展，电气自动化技术已走过了从无到有、从发展到成熟的过程。
而我国电气自动化的研究工作可以追溯到上世纪的五十年代，可以说研究的时间不短，但是它依旧焕发着生气与活力。下文就来简述一下我国电气自动化的发展历程：（一）全空型的电力电子开关。
于上世纪五十年代晶闸管出现了，它标志着运动控制的新纪元。尽管它是第一代电子电力器件，但仍被沿用至今。
随后交流变频技术出现后相继有出现了全控制式器件如GTR等。这是电力电子器件的第二代；接下来是IGBT和MGT这一类复合型电力电子器件可以称为第三代器件。
最后是功率集成电路，PIC即第四代电力电子器件。（二）由低频向高频方向发展的电路。
不断更新的电力电子器件势必要引发变换器电路的换代。当应用于普通晶闸管时，直流传动的变换器主要是整流相互控制，交流变频传动则是交—直—交变频器。
当电力电子器件转换到第二代的时候，PWM变换器采用的相应也要多些。因为采用了PWM变换器之后不仅提高了功效，并且能够减少高次谐波对电网的影响，合理解决了电动机在低频区的转矩脉动问题。
随着应用的深入，PWM也存在着诸多缺陷，因此也就有了谐振式直流逆变器电路的发展。（三）交流调速控制理论。
交流电机磁场定向远离市由德国学者F·Blaschke所提出来的，这一理论的提出为交流传动高性能控制奠定了深刻的理论基础。但他提出的这个思想远不能够达到理论的操控效果。
于是事隔14年后于1985年德国鲁德大学的Depenbrock教授又提出了直接转矩控制的思想，紧接着有将它推放到了弱磁调速的范围内。可以说他的这一控制思想新颖，控制结构简单明了，信号处理的物理概念明确，是一种高静动态性能的新型交流调速方法。
（四）通用变频器的投入使用。通用变频器：系列化、批量化、占市场量最大的中小功率变频器。
先后变频器经历了第一代：普通功能型U/F控制型；第二代：高功能型U/F型；第三代：高动态性能适量控制型。（五）单片机的发展。
占主导地位的MCS-51的8位机虽占主导地位，但是它的功能还比较简单，指令集短小，因此就有了适合大批量生产的PIC系列单片机的推广使用，它不仅具有很高的可靠性，而且保密性高。二、电气自动化的应用（一）建筑中的应用。
智能化建筑势必要引入电气自动化的成分，随着我国国民经济的飞速发展以及数字电子化科技发展，无疑，高档智能化建筑已经成为了当今建筑界的主流方向。为了达到设备的合理利用，三明的人力的节省就有了建筑设备的自动化控制系统。
例如：在建筑物供配电设计中，接地系统没计占有重要的地位，因为它关系到供电系统的可靠性，安全性。IN—S是一个三相四线J/NPE线的接地系统。
通常建筑物内设有独立变配电所时进线采用该系统。TN—s系统的特点是，中性线N与保护接地线PE除在变压器中性点共同接地外，两线不再有任何的电气连接。
中性线N是带电的，而PE线不带电。该接地系统完全具备安全和可靠的基准电位。
只要像TN—C—S接地系统，采取同样的技术措施，TN—S系统可以用作智能建筑物的接地系统。智能建筑应没置电子设备的直流接地，交流工作接地，安全保护接地及普通建筑也应具备的防雷保护接地。
智能化建筑内有大量的电子设备与布线系统，如通信自动化系统，火灾报警及消防联动控制系统，楼宇自动化系统，保安监控系统，办公自动化系统，闭路电视系统等，以及他们相应的布线系统。这些电子设备及布线系统一般均属于耐压等级低，防干扰要求高，最怕受到雷击的部分。
建立严密，完整的防雷结构。智能建筑多属于一级负荷，应按一级防雷建筑物的保护措施设计，组成具有多层屏蔽的笼形防雷体系。
（二）应用于净化空调设备。净化空调系统控制自动监控装置，可设计成单个系统的测量、控制系统，也可设计成数字计算机控制管理系统。
对温度的控制。净化空凋系统采用DDC控制。
装设在回风管（回风温度近似于洁净室温度）的温度传感器所检测的温度送往DX一9100，与设定点相比较，用比例加积分加微分运算进行控制，输出相应电压信号，控制加热电动调节阀或冷水电动调节阀的动作，控制回风温度保持在18"12—26'℃之间，使洁净室温度符合GMP要求。对湿度的控制。
装设在同风管（回风湿度近似丁洁净室湿度）内的湿度传感器所检测的湿度，送往控制器与设定湿度相比较，用比例加积分运算控制，输出电JK信号，控制蒸汽电动调节阀的动作，控制回风湿度保持在45%.65%，使洁净室湿度以满足GMP要求。电气自动化技术。

Introduction to Civil Engineering PapersCivil Engineering for the development of a key role, first as a material foundation for the civil engineering construction materials, followed by the subsequent development of the design theory and construction technology. Every time a new quality of building materials, civil engineering will be a leap-style development. People can only rely on the early earth, wood and other natural materials in the construction activities, and later appeared in brick and tile that artificial materials, so that the first human to break the shackles of natural building materials. China in the eleventh century BC in the early Western Zhou Dynasty created the tile. The first brick in the fifth century BC to the third century BC, when the tomb of the Warring States Period. Brick and tile better than the mechanical properties of soil, materials, and easy to manufacture. The brick and tile so that people began to appear widely, to a large number of housing construction and urban flood control project, and so on. This civil engineering technology has been rapid development. Up to 18 to the 19th century, as long as two thousand years, brick and tile has been a major civil engineering construction materials, human civilization has made a great contribution to the even was also widely used in the present. The application of a large number of steel products is the second leap in civil engineering. Seventeen 1970s the use of pig iron, the early nineteenth century, the use of wrought iron bridges and the construction of housing, which is a prelude to the emergence of steel. From the beginning of the mid-nineteenth century, metallurgical industry, smelting and rolling out high tensile and compressive strength, ductility, uniformity of the quality of construction steel and then produce high-strength steel wire, steel cables. As a result of the need to adapt to the development of the steel structure have been flourishing. In addition to the application of the original beam, arch structure, the new truss, a framework, the structure of network, cable structures to promote the gradual emergence of the structure of Yan in the form of flowers. From the brick building long-span structures, stone structures, a few meters of wood, steel structure to the development of tens of meters, a few hundred meters, until modern km above. So in the river, cross the bridge from shelves, on the ground since the construction of skyscrapers and high-rise tower, even in the laying of underground railway, to create an unprecedented miracle. In order to meet the needs of the development of steel works, on the basis of Newton's mechanics, material mechanics, structural mechanics, structural engineering design theory came into being, and so on. Construction machinery, construction technology and construction organization design theory also development, civil engineering from the experience of rising to become science, engineering practice and theoretical basis for both is a different place, which led to more rapid development of civil engineering. During the nineteenth century, 20, made of Portland cement, concrete has come out. Concrete can aggregate materials, easy-to-concrete structures forming, but the tensile strength of concrete is very small, limited use. By the middle of the nineteenth century, the surge in steel production, with the emergence of this new type of reinforced concrete composite construction materials, which bear the tension steel, concrete bear the pressure and play their own advantages. Since the beginning of the 20th century, reinforced concrete is widely used in various fields of civil engineering. From the beginning of the 1930s, there have been pre-stressed concrete. Pre-stressed concrete structure of the crack resistance, rigidity and carrying capacity, much higher than the reinforced concrete structure, which uses an even wider area. Civil Engineering into the reinforced concrete and prestressed concrete dominant historical period. Concrete buildings to bring about the emergence of new economic, aesthetic structure in the form of engineering, civil engineering so that a new construction technology and engineering design of the structure of the theory. This is another leap in the development of civil engineering. A project to build the facilities in general to go through the investigation, design and construction in three stages, require the use of geological prospecting projects, hydro-geological survey, engineering survey, soil mechanics, mechanical engineering, engineering design, building materials, construction equipment, engineering machinery, building the economy , And other disciplines and con。
7.急求一篇有关办公自动化系统方面的英文论文加翻译,字数3000字左右
办公自动化系统是人机信息系统，是办公自动化技术与管理科学、行为科学、组织理论等相融合，贯穿到办公活动的各个方面，并对这些方面产生一系列影响之后形成的系统，其目的是尽可能充分利用信息资源，提高办公质量和办公效率。
办公自动化系统是一种人机信息系统，具有一般信息系统的共性。同时，由于办公过程和办公活动具不有确定性，人在系统中应始终处于主导地位。办公的主体是办公人员，设备只是服务于人的技术手段。建立办公自动化系统后，人的办公活动和社会组织的办公过程已离不开设备的运行，而是与其结合在一起形成一个统一的系统。建立办公自动化系统的目的并不单纯是提高办公效率或减少办公人员，而首先是为了提高办公质量，在提高办公质量和办公效率的基础上，通过各种决策模型及时提供辅助决策的信息，以实现科学管理和科学决策。此外，办公自动化系统是一个开放式的系统。在设计和建立系统时，应充分考虑和社会环境的连接。
办公自动化系统的功能与办公室自动化的功能概念上存在差别。办公室自动化功能通常指办公室中配备具有自动化功能的设备，这些设备能使某些办公活动自动化或实现某个单位业务的自动化处理；而办公自动化系统则是在办公室自动化功能的基础上发展起来，以办公自动化技术为主体，同人、组织、制度、环境等相结合的完整的系统。
