2015年电大汽车电工电子基础及电路分析作业1-3答案 (2)

电大汽车电工电子基础及电路分析作业1这里讲解为1、2、3、4、5、6等，要求对电路的基本概念和知识能灵活应用。1、要求学生掌握电路的相关基本概念。答案A、发出功率B、发出功率C、吸收功率D、吸收功率2、理想电压源不能互换。互换条件为USISR0，R0RS3、电流控制电压源、电流控制电流源、电压控制电压源、电压控制电流源4、简述电路空载和短路的特征。电路开路（空载）（1）I0；（2）UL0；（3）电源内阻无压降；（4）输出功率为0。电路短路（1）IS非常大；（2）UL0；（3）电源内阻功率大；（4）输出功率为0。5、ARUIS01MRI226、0I0，UUS，P01，UIR1，PUIARUIS412，UIR2，PUI2IS3，U0，P0SRUI汽车电工电子基础及电路分析作业2要求对半导体元件的基本特性进行掌握，对放大电路的基本分析方法能熟练掌握。这里这种讲解计算题的第2、3题。2、根据二极管的单向导电性，当UIE时，二极管导通，UOE；反之，二极管截止，UOUI。3、（1）先进行静态工作点分析EBBERVCI3021BICCEEIRVU（2）微变等效电路BELCIOURRA/输入电阻RIRS/RB/RBE33/10/0795输出电阻RORCBERCRLIS汽车电工电子基础及电路分析作业3要求对运算放大电路和数字电路的基本分析方法能熟练掌握。这里这种讲解计算题的第1、2、3题。1、FABBCAC，表决电路2、理想运放在线性应用时的两个重要特性（1）输出电压UO与输入电压之间满足关系式UOAUD（UU）由于AUD，而UO为有限值，因此，UU0。即UU，称为“虚短”。（2）由于RI，故流进运放两个输入端的电流可视为零，即IIB0，称为“虚断”。这说明运放对其前级吸取电流极小。上述两个特性是分析理想运放应用电路的基本原则，可简化运放电路的计算。所以110URF03、CBACABF请您务必删除一下内容，O_O万分谢谢2015年中央电大期末复习考试小抄大全，电大期末考试必备小抄，电大考试必过小抄INDONESIAHASEMERGEDASATOPVACATIONDESTINATIONFORCHINESETHISSUMMER,ALONGWITHTHAILANDSPHUKETISLANDANDTHEMALDIVESARCHIPELAGOENCOURAGEDBYGROWTHINCHINESETRAVELERSTOINDONESIA,THEGOVERNMENTINJAKARTAHASRECENTLYRELAXEDITSVISAPOLICYSINCEJUNE10,CHINESETOURISTSCANENTERINDONESIATHROUGHNINEAPPOINTEDLOCATIONS,INCLUDINGTHESOEKARNOHATTAINTERNATIONALAIRPORTINJAKARTA,THENGURAHRAIINTERNATIONALAIRPORTINBALIANDTHEKUALANAMUINTERNATIONALAIRPORTINMEDAN,BYJUSTGETTINGTHEIRPASSPORTSSTAMPEDONARRIVALOFFICIALLY,ITISCALLEDTHE“FREEVISA“SCHEMETHENEWPOLICYALSOMEANSCHINESETOURISTSCANSAVE35ONVISAFEES,WHICHWILLLIKELYMAKETRIPSTOINDONESIAMOREALLURINGWHILESUCHANARRANGEMENTALLOWSCHINESEVISITORSTOSTAYUPTO30DAYSFORTHEPURPOSEOFTRAVELING,THOSESEEKINGEXTENSIONSWILLNEEDTOGETPAIDVISASFROMTHATCOUNTRYSMISSIONSINBEIJING,SHANGHAI,GUANGZHOUORHONGKONG,ACCORDINGTOANOFFICIALATTHEINDONESIAEMBASSYINBEIJINGSANTODARMOSUMARTO,HEADOFTHEEMBASSYSINFORMATION,SOCIALANDCULTURALSECTION,SAYSTHENEWPOLICYISAIMEDATSTRENGTHENINGPEOPLETOPEOPLECONTACTSBETWEENTHETWOCOUNTRIESDAIYU,MARKETINGDIRECTOROFCTRIP,AMAJORCHINESEONLINETRAVELAGENCY,SAYS“WEVESEENANEARLY50PERCENTGROWTHOVERTHEPREVIOUSMONTHINTHENUMBEROFCHINESETOURISTSTOBALISINCETHEPOLICYWASANNOUNCED“DURINGHISTRIPTOCHINAINMARCH,INDONESIANPRESIDENTJOKOWIDODOPROPOSEDTHATHISCOUNTRYANDCHINAAIMTOINCREASETWOWAYVISITSTOAMAXIMUMOF10MILLIONPEOPLEINTHENEXTFEWYEARSTHEINDONESIANGOVERNMENTHASSETTHEIRSIGHTSONGREETING2MILLIONCHINESETOURISTSBYTHEENDOFTHISYEAR,ACCORDINGTOTHEOFFICIAL“THEINDONESIANGOVERNMENTHOPESTHATINDONESIANNATIONALSWOULDALSOBEGIVENPREFERENTIALTREATMENTWHILEVISITINGCHINA,“SAYSDARMOSUMARTOIN2013,THENUMBEROFCHINESETOURISTSWHOVISITEDINDONESIASTOODAROUND807,000LASTYEAR,ITINCREASEDTO959,000,HEADDSBALIREMAINSTHEMOSTPOPULARSITEAMONGCHINESETOURISTSINFEBRUARY,MORETHAN92,200CHINESETOURISTSMADETRIPSTOBALI,RANKINGFIRSTAMONGOVERSEASVISITORS,THEBALITIMESREPORTEDLASTYEAR,THEISLANDWITNESSEDMORETHAN586,000ARRIVALSFROMCHINA,ANINCREASEOF51PERCENTOVER2013“BALIISNTJUSTFORSIGHTSEEING,BUTALSOFORWEDDINGS,HONEYMOONS,GOLFANDMANYOUTDOORACTIVITIES,“SAYSFANWENQING,AMARKETINGEXECUTIVEATGARUDA,INDONESIASNATIONALAIRLINERGARUDAOFFERSTHREENONSTOPFLIGHTSBETWEENBEIJINGANDBALI,ANDFOUREACHWEEKBETWEENBEIJINGANDJAKARTATHEREAREDAILYFLIGHTSFROMGUANGZHOU,INGUANGDONGPROVINCE,ANDSHANGHAITOJAKARTAASWELLITTAKESFROMSIXTOEIGHTHOURSONANONSTOPFLIGHTTOREACHINDONESIAFROMCHINAINDONESIAISHOMETOMORETHAN17,000ISLANDSTOURISTSCANTOURYOGYAKARTATOSEEPRAMBANAMANDBOROBUDUR,TWOHISTORICALANDRELIGIOUSSITES,ANDEXPLORETHELOCALHANDICRAFTMARKETSTHEBASEOFAVOLCANO,BANDUNG,WHICHISALSOKNOWNASTHE“PARISOFJAVA“,ISIDEALFORADVENTURESEEKERSMANYECOTOURISMDESTINATIONS,SUCHASTOBALAKEINSUMATRA,TANJUNGPUTINGNATIONALPARKINKALIMANTANANDBUNAKENINMANADO,AREPLACESTHEEMBASSYOFFICIALRECOMMENDSFORTOURISTSINDONESIABOASTSWORLDCLASSSURFINGFACILITIESALONGTHESHORESOFSUMATRADOWNTONUSATENGGARAISLANDSRECENTLY,LOMBOK,ASISTERISLANDEASTOFBALIHASGOTTENSOMUCHATTENTIONFROMCHINESETRAVELERSTHATSOMETRAVELAGENCIESAREOFFERINGTWINPACKAGESFORBALIANDLOMBOKTHEBESTTIMETOVISITBALIISFROMMAYTOOCTOBER,WHENITDOESNTRAINMUCHANDTHEWEATHERISCOOLATPRESSTIME,AWEEKLONGPACKAGEFROMSHANGHAIORGUANGZHOUTOBALIWASALITTLEMORETHAN3,000YUAN480ONCTRIPSWEBSITECHINESETOURISTSHAVETAKENASHINETORAFTINGINUBUD,SIGHTSEEINGINTANAHLOT,ANDSURFINGANDDIVINGINNUSALEMBONGAN,SAYSDAICIVETCOFFEE,ESSENTIALOILANDWOODCARVINGSAREAMONGTHEMOSTPOPULARPRODUCTSFORCHINESETOURISTSININDONESIA,SHESAYSINDONESIANFOODISALSOSOMETHINGTHATVISITORSSHOULDNTMISSLOCALCUISINESFEATUREMANYSPICES,INCLUDINGPEPPERSANDCLOVES,ANDCOCONUTPULPFRIEDRICE,“DIRTYDUCK“ANDROASTSUCKLINGPIGARERECOMMENDEDCHILDRENSILLUSTRATIONBOOKSFIRSTAPPEAREDINTHE1600SINEUROPETHEIRPASSAGETOCHINA,HOWEVER,TOOKMUCHLONGER,ROUGHLY300YEARSINCHINA,CHILDRENSILLUSTRATIONBOOKSHAVEAHISTORYOFJUST100YEARSANDTHEIRDEVELOPMENTCANBEDIVIDEDINTOFOURSTAGESFROMEARLY1900STOMID1900S,ALARGENUMBEROFBOOKSANDMAGAZINESWITHILLUSTRATIONSAPPEAREDWITHTHEFASTDEVELOPMENTOFTHEMODERNPUBLISHINGINDUSTRYTHEILLUSTRATIONARTSATTHATTIMEWEREAMIXEDGENREOFCHINESETRADITIONALPAINTINGSANDTHEWESTERNSTYLE,ANDMOSTOFTHESTORIESORIGINATEFROMTHEFUNDAMENTALCHANGESTHATCHINAEXPERIENCEDAFTERTHECOLLAPSEOFQINGDYNASTY16441911,THEWARLORDSTRUGGLESANDTHEWARAGAINSTTHEJAPANES
