测控技术与仪器专业英语阅读翻译篇一:测控技术与仪器专业英语课后阅读翻译(1,5~10)第1章课后,,,???,,,?,,??,?,,(1950),,??,,??,;,,,(,),,,,,,=(2),,,(),水下声波信号在声纳操作过程中,操作员经常需要对受噪声干扰的信号进行检波。
干扰信号可能来自操作员发出信号的反射波或者外部声源的信号。
这两种类型的干扰对主动声纳和被动声纳都会造成很大影响。
类似的情况在雷达监测、工程类和图像类专业的基本原理都会涉及到。
当你想到信号检测时有多种方法,那么定义一个术语来表示特殊情况便是可行的。
当问题的答案是“当前有一个还是一个多个信号?”时,检波一词将被使用。
一个系统被设计来为这种问题提供答案--无论是必然性还是偶然性,这就需要谈及假设检验;当一个信号反复出现的情况下,许多系统只被设计提供两个答案:“是的,当前有一个信号”或“不,当前没有信号”。
力图将信号分类会使问题复杂化,因为后者的结论将涉及到目标分类。
一般来说,一种检波仪器只被设计在固定的类型和参数下工作,不容易被改变,例如时间积分检波电路和光学检测的辉光示波管。
当出现不明信号时,观察者在拒绝或接收信号方面有所迟疑。
在这种情况下,操作员会有种感觉如果检波电路或者示波管能够延长时间那么他就能下结论该信号是否存在。
沃尔德(1950)在他的检波理论系统阐述了这种直觉。
如果(一个检测检测方法)能够主动去改变时间间隔并在接收系统里储存数据以便达到确定的某一水平,这就是顺序检测。
一般不仅能够确定信号存在与否,而且还能确定一个或多个与信号关联的参数。
在还原完整波形时我们所感兴趣的参数在各简单分量间有很大差别,例如信号的到达时间和相位。
当一个系统被设计来提取一个或多个信号参数时,这就是信号抽取。
信号一词并没有明确的定义,只是在读者对它有直观了解时的一种假设。
有些较为详细的解释为了对信号一词进定义可能导致是比较主观的或者狭隘与所应用的条件。
Unit 1 Definition of Measurement and Measurement Theory定义的测量方法和测量理论1. Definition of Measurement测量的定义A possible operational description of the term measurement which agrees with our intuition is the following :“measurement is the acquisition of information ”;the aspect of gathering information is one of the most essential aspects ofmeasurement ;measurement are conducted to learn about the object of measurement ;the measurand .This means that a measurement must be descriptive with regard to that state or that phenomenon in the world around us which we are measuring .一个可能的操作描述这个术语的同意,我们凭直觉测量是下列的“测量信息获取”,采集信息的方面是最重要的方面进行测量,计量了解测量的对象,进行测量。
这意味着一个测量必须描述对于这种状态或这一现象在我们周围的世界我们衡量。
There must be a relationship between this state or phenomenon and the measurement result .Although the aspect of acquiring information is elementary ,it is merely a necessary and not a sufficient aspect of measurement :when one reads a textbook ,one gathers information ,but one does not perform a measurement.必须有一个关系状态或现象和测量结果信息获取的角度,即使是基础,那只是一个必要的和非充分方面的测量:当一个人阅读教科书,一个收集信息,但是一个人不能进行测量。
测控技术与仪器专业英语教程(第2版)课后答案第一章1.简谐信号是最简单和最重要的周期信号。
任意一个周期信号可以用简谐信号来表达,两者之间联系的桥梁是傅里叶级数,所以傅里叶级数是周期信号分析的理论基础。
翻译:Harmonic signal is the simplest and the most important periodic signal. Any one of the periodic signal can use harmonic signal to express, contact between the bridge is Fourier series, so Fourier series is periodic signal analysis of the theoretical basis.2.一个在时域上显得很复杂的信号,将其变换或映射到频域(包括s和z域),就能够分解为非常简单的基本信号形式,进行分析和求解。
翻译:A time domain appear very complex signal, its transformation or mapping to the frequency domain (including s and z domain), can be decomposed to A very simple basic signal form, carries on the analysis and solution.第二章1.信号不是周期性出现,而只是持续一段时间,不再重复出现,如过渡过程、爆炸产生的冲击波、起落架着陆时的信号等,把这一类信号看成为非周期信号。
分析非周期信号的思路是:在时域上,当周期A,周期信号变成为非周期信号:在频域上,周期信号的频谱在A 时的极限,变为非周期信号的频谱,即傅里叶变换。
翻译:Signals are not periodic appear, but only for a period of time, and shall not repeat appear, such as the transition process from an explosion, the shock wave, landing gear landing signal, this kind of signal see as a periodic signal. Analysis of the thinking of the periodic signal in time domain, when A cycle, cycle signal into non periodic signal: in the frequency domain,the signal spectrum in A cycle of limit, A non periodic signal spectrum, namely Fourier transform.2.信号在时域压缩α倍(α>0)时,则在频域中频带加宽,幅值压缩1/α倍;反之信号在时域扩展时(α<1),在频域中将引起频带变窄,但幅值增高。

仪器工程师负责控制整个系统,比如一个电厂。
An instrument is a device that measures and/or regulates process variables such as flow, temperature, level, or pressure. Instruments include many varied contrivances that can be as simple as valves and transmitters, and as complex as analyzers.译为:仪器是一种用来测量和/或调节过程变量(如流量、温度、液位或压力)的装置。
仪器包括许多不同的设备,可以像阀和变送器那样简单,也可以像分析仪那样复杂。
Instruments often comprise control systems of varied processes such as refineries, factories, and vehicles. The control of processes is one of the main branches of applied instrumentation. Instrumentation can also refer to handheld devices that measure some desired variable. Diverse handheld instrumentation is common in laboratories, but can be found in the household as well. For example, a smoke detector is a common instrument found in most western homes.译为:仪器通常由如精炼厂、工厂和车辆这些不同流程的控制系统组成。
过程控制是实用仪器的主要分支之一。
仪器也可以是测量某个所需变量的手持设备。
多样化的手持式仪器常见于实验室,在日常生活中也可以发现。
例如:烟雾探测器是西方家庭中的一种常见仪器。
Output instrumentation includes devices such as solenoids, valves, regulators, circuit breakers, and relays. These devices control a desired output variable, and provide either remote or automated control capabilities. These are often referred to as final control elements when controlled remotely or by a control system.句中desired output variable意为“期望输出变量”,are referred to as意为“被称为”。
全句译为:输出仪器包括线圈、阀、调节器、断路器和继电器等元件。
这些元件控制期望输出变量,使之实现远程或自动控制功能。
在远程控制或自动控制系统中,称这些元件为终端控制元件。
Transmitters are devices that produce an output signal, often in the form of a 4~20mAelectrical current signal, although many other options using voltage, frequency, pressure, or ethernet are possible. This signal can be used for informational purposes, or it can be sent to a PLC, DCS, SCADA system, LabView or other type of computerized controller, where it can be interpreted into readable values and used to control other devices and processes in the system.译为:变送器是产生某种输出信号的装置,通常是4—20mA的电流信号,当然也可以是电压、频率、压力或以太网。
这个信号可作参考之用,还可以发送到PLC、DCS、SCADA 系统、LabView或其它类型的计算机控制器,这个信号被转换成可读值,用于控制系统中的其它设备和过程。
Control Instrumentation plays a significant role in both gathering information from the field and changing the field parameters, and as such are a key part of control loops.句中field意为“现场”,control loops意为“控制回路”。
全句译为:控制仪器在现场信息采集和现场参数转换中都起到了重要作用。
这本身是控制回路的一个关键部分。
HistoryIn the early years of process control, process indicators and control elements such as valves were monitored by an operator that walked around the unit adjusting the valves to obtain the desired temperatures, pressures, and flows. As technology evolved pneumaticcontrollers(气压式调节器) were invented and mounted(安装,配有)in the field that monitored the process and controlled the valves.译为:在早年的过程控制中,过程指标和控制元件,如阀,是由操作员在装置周围走动通过调节阀门来监测,以获得所需的温度、压力和流量。
随着技术的发展,气压式调节器发明了,并安装于监测过程和控制阀的现场。
This reduced the amount of time process operators were needed to monitor the process. Later years the actual controllers were moved to a central room and signals were sent into the control room to monitor the process and outputs signals were sent to the final control element such as a valve to adjust the process as needed.译为:这样就减少了过程操作员监测过程所需的时间。
近几年,实际控制转移到中央控制室,信号被发送到控制室来监测过程,并且输出信号被送到终端控制元件,如阀门,根据需要调节过程。
These controllers and indicators were mounted on a wall called a control board.译为:这些控制器和指示器安装称为控制面板的壁面上。
The operators stood in front of this board walking back and forth monitoring the process indicators. This again reduced the number and amount of time process operators wereneeded to walk around the units. The basic air signal used during these years was 3~15 psig(磅/平方英寸).译为:操作员在面板前面来回走动以监测过程指示器。
这就再次减少了过程操作员在装置周围来回走动所需的时间。
这几年使用的基本气压信号是3-15磅/平方英寸。
In the 1970s electronic instrumentation began to be manufactured by the instrument companies. Each instrument company came out with their own standard signal for theirinstrumentation, 10~50mA, 0.25~1.25V, 0~10V, 1~5V, and 4~20mA, causing only confusion until the 4~20mA was universally used as a standard electronic instrument signal for transmitters and valves.译为:20世纪70年代仪器公司开始生产电子仪器。
每个仪器公司为他们的仪器装置推出了自己的标准信号:如10~50mA, 0.25~1.25V, 0~10V, 1~5V, 和4~20mA,这只会引起混乱,直到4~20mA被普遍作为变送器和阀的标准电子仪器信号。
The transformation of instrumentation from mechanical pneumatic transmitters, controllers, and valves to electronic instruments reduced maintenance costs as electronic instruments were more dependable than mechanical instruments. This also increased efficiency and production due to their increase in accuracy.句中reduced为transformation的谓语,as引导原因状语从句。
