世界观人人都有,而哲学只有经过系统的学习的人才能掌握它。世界观是自发成的,是不系统的、不自觉的、缺乏严密的逻辑和理论论证,而哲学则是把自发的、零散的、朴素的世界观加以理论化和系统化,因而具有严密的逻辑和完整的理论体系。appearanceoftheweldappearancequalitytechnicalrequirementsoftheprojectmustnothaveamoltenmetalstreamdoesnotmeltthebasemetaltoweld,weldseamandheat-affectedzonesurfacemustnothavecracks,pores,defectssuchascraterandash,surfacesmoothing,weldandbasemetalshouldbeevenlysmoothtransition.Width2-3mmfromtheedgeofweldGroove.Surfacereinforcementshouldbelessthanorequalto1+0.2timestheslopeedgewidth,andshouldnotbegreaterthan4mm.Depthofundercutshouldbelessthanorequalto0.5mm,totallengthoftheweldsonbothsidesundercutnotexceed10%oftheweldlength,andlongcontinuousshouldnotbegreaterthan100mm.Wrongsideshouldbelessthanorat0.2T,andshouldnotbegreaterthan2mm(wallthicknessmmt)incompleteornotallow7.57.5.1installationqualityprocessstandardsoftheelectricalenclosureCabinetsurfaceisclean,neat,nosignificantphenomenonofconvex,closetonature,closethedoor.7.5.2CabinetCabinetfacepaintsnopaint,returnedtorusted,consistentcolor.7.5.3uniformindirectgapfromtoptobottom,slotwidth1.5mm7.5.4adjacentCabinetsurfaceroughnessis0.7.5.5thecabinetsfirmlyfixed,craftsbeautiful.7.5.6Cabinetsurfacegauge,switchcabinetmarkclear,neat,firmpaste.7.5.7Terminalrowofneat,isreliable,theappearanceiscleanandnotdamaged.7.5.8cablesneatandclean,solidbinding,bindingprocessinappearance.7.5.9thefirstcableproductionfirm,craftsbeautiful,clearsignagedoesnotfade.7.5.10fireproofpluggingtight,nocracksandpores.7.67.6.1ofthestandardelectricalwiringqualitytechnologycablea,themulti-corewirebuncharrangementshouldbeparalleltoeachother,horizontalwireharnessorwireshouldbeperpendiculartothelongitudinalmulti-corewirebunch.Thedistancebetweenthewireharnessandwireharnesssymmetry,andascloseaspossible.B-corewiringharnessintoround,multi-corewirebunchusedgwirebinding,fastening诚信应考,考试作弊将带来严重后果!华南理工大学期中考试《中级微观经济学》试卷注意事项:1.考前请将密封线内各项信息填写清楚;2.所有答案请直接答在试卷上;3.考试形式:闭卷;4.本试卷共八大题,满分100分,考试时间120分钟。题号一二三四五六七八总分得分评卷人1.1984年,美国实行的食品券计划涉及2100万人,共花费120亿美元。假设某一家庭有资格得到食品券,每月支付80美元就可以买到150美元的食品。(10分)(1)如果家庭每月的货币收入为250美元,不符合领取食品券条件,用图形表示该预算线;(2)如果家庭符合领取食品券条件,请画出该家庭的预算线;(3)说明如果这个家庭得到70美元的现金而非实物食品时,可以达到更高的满足水平。略2、写出消费者的效用函数:(6分)(1)消费者认为2单位的X1和6单位的X2无差异。(2)消费者总是将3单位的X1和8单位的X2搭配消费。解:(1)U=6X1+2X2;(2)U={8X1,3X2}3、分别画出两种商品都是正常商品、一种正常商品一种劣质品,一种正常商品一种吉芬商品的收入扩展曲线和价格提供曲线。(12分)(说明:正常商品用横坐标表示)看PPT.4.效用函数形式为,商品1和2的价格分别为P1和P2,收入为m,求效用最优化的消费束。(12分)5.Carlos曾经在阿根廷、哥伦_____________________…姓名学号学院专业座位号(密封线内不答题)……………………………………………………密………………………………………………封………………………………………线……………………………………线………………………………………/1221)(),(1xxxxu)1/(2)1/(1)1/(122)1/(2)1/(1)1/(11121221122211221,0,0)()ln(1..)ln(1),(max11ppmpxppmpxxLxLxpxpmxxLmxpxptsxxxxu解得:世界观人人都有,而哲学只有经过系统的学习的人才能掌握它。世界观是自发成的,是不系统的、不自觉的、缺乏严密的逻辑和理论论证,而哲学则是把自发的、零散的、朴素的世界观加以理论化和系统化,因而具有严密的逻辑和完整的理论体系。appearanceoftheweldappearancequalitytechnicalrequirementsoftheprojectmustnothaveamoltenmetalstreamdoesnotmeltthebasemetaltoweld,weldseamandheat-affectedzonesurfacemustnothavecracks,pores,defectssuchascraterandash,surfacesmoothing,weldandbasemetalshouldbeevenlysmoothtransition.Width2-3mmfromtheedgeofweldGroove.Surfacereinforcementshouldbelessthanorequalto1+0.2timestheslopeedgewidth,andshouldnotbegreaterthan4mm.Depthofundercutshouldbelessthanorequalto0.5mm,totallengthoftheweldsonbothsidesundercutnotexceed10%oftheweldlength,andlongcontinuousshouldnotbegreaterthan100mm.Wrongsideshouldbelessthanorat0.2T,andshouldnotbegreaterthan2mm(wallthicknessmmt)incompleteornotallow7.57.5.1installationqualityprocessstandardsoftheelectricalenclosureCabinetsurfaceisclean,neat,nosignificantphenomenonofconvex,closetonature,closethedoor.7.5.2CabinetCabinetfacepaintsnopaint,returnedtorusted,consistentcolor.7.5.3uniformindirectgapfromtoptobottom,slotwidth1.5mm7.5.4adjacentCabinetsurfaceroughnessis0.7.5.5thecabinetsfirmlyfixed,craftsbeautiful.7.5.6Cabinetsurfacegauge,switchcabinetmarkclear,neat,firmpaste.7.5.7Terminalrowofneat,isreliable,theappearanceiscleanandnotdamaged.7.5.8cablesneatandclean,solidbinding,bindingprocessinappearance.7.5.9thefirstcableproductionfirm,craftsbeautiful,clearsignagedoesnotfade.7.5.10fireproofpluggingtight,nocracksandpores.7.67.6.1ofthestandardelectricalwiringqualitytechnologycablea,themulti-corewirebuncharrangementshouldbeparalleltoeachother,horizontalwireharnessorwireshouldbeperpendiculartothelongitudinalmulti-corewirebunch.Thedistancebetweenthewireharnessandwireharnesssymmetry,andascloseaspossible.B-corewiringharnessintoround,multi-corewirebunchusedgwirebinding,fastening比亚和玻利维亚住过。他只买两种商品x和y。在阿根廷,两商品的价格为($9,$3),他的消费束为(6,7);在哥伦比亚,两商品的价格为($3,$3),他的消费束为(6,5);在玻利维亚,他的消费束为(9,2)。请问他在玻利维亚的状况与阿根廷相比是更好、更差还是不能判断?(12分)解:阿根廷更好。阿根廷(6,7)哥伦比亚(6,5)玻利维亚(9,2)(9,3)7669D87(3,3)393333D阿根廷直接显示偏好于哥伦比亚,哥伦比亚直接显示偏好于玻利维亚,可知阿根廷间接显示偏好于玻利维亚。6.在70年代石油危机的时候,有一项政策建议是先提高汽油税(从量税为t),减少消费者对汽油的消费,然后将通过汽油税从消费者那里征得的税收(根据最初的消费量进行退税)再直接以货币的形式退还给消费者。(汽油以x表示,其他商品以y表示)。分析:(18分)(1)写出征税前和征税后及征税退税情况下的预算约束方程;(2)作图说明,政策实施后汽油消费量和消费者状况会有什么变化?此时,假设汽油税最终会全部转嫁给汽油的消费者,汽油价格的上涨幅度恰好等于税收量。(3)消费者的境况是变好了还是变差了?(注:此问可以不用做图。)解:(1)征税
