装 订 线
A multimeter is a general-purpose meter capable of measuring
voltage, , , and in some cases, decibels. There are two types of meters: using a standard meter movement with a needle (see Fig 3.1(a)), and , with an electronic numerical display (see Fig 3.1(b)).
Both types of meters have a (+) jack and a jack (-) for the test leads，to select dc voltage, ac voltage, dc current, ac current, or ohms and for accurate readings. The meters may also have other jacks to measure (1 to 5 kV) and current (up to 10A) there are some variations to the functions used for specific meters.
1)Resistance 2)placed across (in parallel) 3)be removed
4)in series with 5)mechanical adjust 6)automatic indicator
5)properly 8) test leads 9)correct 10)be opened
Besides the function and range switches (sometimes they are in a single switch.) The analog meter may have a polarity switch to facilitate reversing the test leads. The needle usually has a screw for to set it to zero and also a zero adjust control to compensate for weakening batteries when measuring . An analog meter can read positive and negative voltage by simply reversing the or moving the polarity switch. A digital meter usually has an for polarity on its display.
Meters must be connected to a circuit to ensure a reading. A voltmeter is always the circuit or component to be measured. When measuring current, the circuit must and the meter inserted the circuit or component to be measured. When measuring the resistance of a component in a circuit, the voltage to the circuit must and the meter placed in parallel with the component.
三.Read the following passage and answer the questions.（5*8=40）
Robots
Robots produce mechanical motion that,in most cases,results in manipulation or locomotion.For example,industrial robots manipulate parts or tools to perform manufacturing tasks such as material handing,welding,spray painting,or assembly;automated guided vehicles are used for transporting materials in factories and warehouses.Telerobots provide astronauts with large mainipulators for remotely performing spacecraft maintenance.
Robots perform repetitive,high-precision operations 24 hours a day without fatigue.Robots on this automobile assembly line weld body parts together.The General Motors corporation uses about 16,000 robots to weld,assemble,and paint automobiles.
Walking robots explore active volcanoes.Mechanical characteristics for robots include degrees of freedom of movement,size and shape of the operating space,stiffness and strength of the structure ,lifting capacity,velocity ,and acceleration
under load.Performance measures include repeatability and accuracy of positioning,speed,and freedom from vibration.
A robot is made up of sensors,actuators,and computatlonal elements(a microprocessor).Actuators for moving joints of a robot are usually electric servomotors.In the past ,larger robots were built with hydraulic actuation due to their high payload capacity and ability to work in explosion-prone environments.In the 1990s,there was a trend by the major manufacturers to use electric actuators in most of their industrial robots.
A robot is an automatically controlled, reprogrammable, multipurpose, manipulating machine with several reprogrammable axes, which may be either fixed in place or mobile for use in industrial automation applications.
The key words are reprogrammable and multipurpose because most single-purpose machines do not meet these two requirements. The term “reprogrammable” implies two th ings: The robot operates according to a written program, and this program can be rewritten to accommodate a variety of manufacturing tasks. The term “multipurpose” means that the robot can perform many different functions, depending on the program and tooling currently in use.
Over the past two decades, the robot has been introduced into industry to perform many monotonous and often unsafe operations. Because robots can perform certain basic tasks more quickly and accurately than humans, they are being increasingly used in various manufacturing industries.
1.What industrial robots can do for people?
2.What are the advantages of robots?
3. What parts are made up of the robot?
4．What does t he term “reprogrammable” impl y?
5.Why are robots widely used over the past two decades?
四.Read the following passage and t ranslate the underlined phrases and sentences into Chinese.（5*4=20）
Classification of Robots
1.Industrial robots vary widely in size, shape, number of axes, degrees of freedom, and design configuration. Each factor influences the dimensions of the robot’s working envelope or the volume of space within which it can move and perform its designated task. A broader classification of robots can been described as below.
Fixed-and Variable-Sequence Robots. The fixed-sequence robot (also called a pick-and place robot) is programmed for a specific sequence of operations. Its movements are from point to point, and the cycle is repeated continuously. 2.The variable-sequence robot can be programmed for a specific sequence of operations but can be reprogrammed to perform another sequence of operation.
3.Playback Robot. An operator leads or walks the playback robot and its end effector through the desired path. The robot memorizes and records the path and sequence of motions and can repeat them continually without any further action or guidance by the operator.
Numerically Controlled Robot. 4.The numerically controlled robot is programmed and operated much like a numerically controlled machine. The robot is servo-controlled by digital data, and its sequence of movements can be changed with relative ease.
5.Intelligent Robot. The intelligent robot is capable of performing some of the functions and tasks carried out by human beings. It is equipped with a variety of sensors with visual and tactile capabilities.

英语作业及答案
下面的范文中有很多错误，请找出形容词与副词的混淆、冠词的遗漏和误用、介词和代词的误用等错误，并检查句子的完整性、单词拼写、主谓的一致性、动词和现在分词是否混淆、复数形式、动词的时态、词汇选择、词性、单词的顺序等问题。 (几乎每个句子都有错误) An university education is a goal of many high school students. Some students want to go into a profession that requires an university degree. But there are other professions that do not require a degree, but require certification from a technological college. The reasons why students make decisions to go to technical college instead of university probably have a lot to do with their choice of career, their own academic abilities and their financial situation. First of all, students make their choices for post-secondary education based on the fields that interest them. A student who is interested in medicine might decide to university, into a pre-med program to prepare to become a doctor, or they might go to nursing school or a nursing program in a technical college. Some career choices offer a choice of educational route. The university route is usually more intense and takes longer. For example, an interior designer might take a one or two year program at a college, or choose to do the degree program as a part of the architectural department at a university. Other career choices involve certification that is available at a college, like broadcast journal or
