A、1minB、2minC、10minD、15min正确答案:A7.在电力系统中,一般有哪些电场形式?正确答案:1、均匀电场;2、稍不均匀电场;3、极不均匀电场。
8.均匀电场中沿面闪络电压比纯空气间隙的击穿电压要低,原因是什么?正确答案:如下图所示,均匀电场中插入固体介质后仍能保持界面与电力线平行,看起来似乎固体介质的插入完全不影响原来的电场分布。
其实不然,此时沿面闪络电压已比纯空气间隙的击穿电压低得多,这说明原先的均匀电场发生了畸变,原因为①固体介质与电极吻合不紧密,存在气隙。
由于空气的ε气比固体介质的ε固低,气隙中场强比平均场强大得多,气体中首先发生局部放电。
放电发生的带电质点,到达固体介质表面使原均匀电场畸变,变成不均匀电场,降低了沿面闪络电压。
②固体介质表面吸潮而形成水膜。
水具有离子电导,离子在电场中受电场力作用而沿介质表面移动,在电极附近积聚起电荷,使介质表面电压不均匀,电极附近场强增强。

Our lives would be the same.We would have to use bikes, horses, or our feet to get to places. And wecouldn''t go as far as we are used to going. But we do have cars. With cars, people can come and go as they please. They can work far from home. Many people live in the country. But they work in the city. Most of them get there in cars. This means that there are a lot of cars on the road.Are there too many cars on the road? Some people think so. So they are asking that we take trains and buses. But not everyone can do this. Some people must take their cars. This is because no trains or buses go where they have to go. Maybe other people could go to work with them. Then there wouldn''t be so many cars on the road.What will our lives be like in times to come? Maybe we won''t need cars so much. Maybe more of us will work at home. Maybe trains and buses will go to more places. Then more people will be in them. This will mean more room on our streets and roads.It would be nice if people walk more. They might like to step along a street or road. They would not get far very fast. But they would have the time to look around them. Who knows? They might even feel better, too!1、What's not the possible reason why there are a lot of cars on the road?A、Because everyone likes to drive his own car to do whatever he likes. ?B、Because the number of trains and buses is small.C、Because many people who live in the country go to work in cars in the city.D、Because it is more convenient for people to go to places in cars than other means.2、According to the author, which of the following is not the reason why thenumber of cars willbe reduced in the future?A、More people will work at home.B、Trains and buses will go to more places.C、More people will take buses and trains.D、People won't need so many cars.3、It can be inferred from the passage that __.A、the author thinks that people who are in the city should not live in the countryB、the author thinks that there should be more trains and buses which should go to more placesC、the author wishes that the number of cars would be reduced so that there will be more room on the streets and roadsD、the authors believe that more walk does good to health4、What does the underlined word "please" here mean?A、to goB、to meanD、to love5、What's the writer's opinion in this passage?A、We should use more carsB、We should use fewer cars.C、We should not use carsD、We should take good care of cars.2、Your mobile phone( ⼿机) rings, and instead of the usual electronic signals, it's playing your favorite music. A friend sends you favorite song to cheer you up. One day, a record company might forward new records and music videos to your phone.The mobile business is getting into the music business. For the moment, the interest is in pleasant ring tones, but some companies are hoping to take full advantage of the next generation of mobile phone --- all-purpose gadgets ( ⼩玩意⼉) that blend phone, personal stereo, video player and Internet browser into one.Finally, record companies might send new records and videos to fans who register their numbers.The fans could pass music or songs along to friends--- a kind of musical trading card. Unlike Internet tracks, mobile downloads would be easy for recordcompanies to control, said former record industry official Ralph Simon, who is now chairman of Yourmobile, based in Santa Monica, California."If you pass a song along to other phones through a network, each phone can be charged,"said Simon."It's like going through a toll gate ( 收费站). There's more possibility for copyright control than there is on the Internet."Massachusetts-based Converse is offering a service in Portugal and theNetherlands that lets people record tunes on their voice mail or send music as presents to friends. Finally, people might be able to sing karaoke and pass them along. The company is sure that people will want to use music to reach out and touch someone.1、The underlined word “ blend” in the second paragraph most probably means( )A、sendB、becomeC、mixD、compare2、Record companies ( ) the idea of passing songs and music along mobilephones.A、are worried aboutB、are interested inC、try hard to stopD、take no notice of3、According to Ralph Simon, it would be easier to ( ) through mobile phonenetwork than through the Internet.C、pars along songs and musicD、send voice maid4、"Massachusetts- based Converse" in the six paragraph probably refers to ( ) ?A、a personB、a city in IsraelC、a state of USAD、a company5、All the following are true except( )A、The mobile companies become involved in music businessB、The mobile phone might serve as a stereo, a video play as well as an internet browserC、Your friend might sing karaoke and send it to your phoneD、The mobile network is better than the internet三、填空题 (共 10 题、0 / 20 分 )1、As long as you return the money promptly. I'll lend it to you with (please) ( ).pleasure2、We should try to learn more (economy) ( ) theory and apply it in practice.economic3、All these worries made it (possible) ( ) for her to concentrate on her work.impossible4、(face) ( ) your weak points doesn’t mean looking down upon yourself.Facing / To face5、It was ordered that no smoking (allow) ( ) in the library.

行的次数。(10分)
2. 创建一个简单的Shape继承结构。Shape被定义为基类,Circle,Square,
Triangle定义为Shape的子类;为Circle,Square,Triangle定义合适的数据 成员用于存储坐标、半径等信息;为三个子类定义合适的构造函数以初始化
cout << “Circle::draw()” << endl;

Array<string> as; as[0] = "0"; for (int i=1; i < as.size(); i++) {
as[i] += as[i-1]; } }
三、程序设计(40 分)
3. 创建一个Message类,其构造函数使用一个string型默认值 为”Unnamed”的参数。在构造函数里,用参数初始化其私有string型数据 成员sValue;为Monitor类创建两个重载的print函数,其中一个零参数, 它简单输出sValue的值;另外一个接受一个string型参数,它先输出参数值 作为标题,再输出sValue作为内容。(10分)
enum { size = 100 }; T A[size]; public: };
图形(构造函数参数中给出坐标,半径等信息);为三个子类定义公开函数 draw()用于描绘图形;定义一个全局函数drawShape(Shape& s),该函数 以一个Shape的引用为参数,但能正确地描绘出不同子类型的图形。(20 分) 说明:draw函数内部不用写出具体代码,以下述形式代码代替:
