此房东我曝光过多次，以前也碰到过黑心的，曝光一次就差不多了，这个201栋的房东已经不是用黑心来形容，退房不要押金能退出来就不错了，怀疑有黑社会背景，不然何以如此嚣张，这个房东被曝光多次，希望租房的同胞多多查查当地黑心房东。

Whyisthereanastonishingatmosphericpressureinsidethesun,butnoblackhole?
　　Firstly,thesunisdividedintoseverallevels.Fromthecenterofthesunoutward,tothesolarnucleus,troposphere,andsolaratmosphere,thesunincludesthreeparts:photospherechromosphereandcorona.15%oftheradiusofthesunismadeupofthesolarnucleus.Whenthethermalnucleusreacts,themainwayofreleasinggreatenergyishydrogenfusion.Thelocaldensityofthesolarnucleusis160grams./Thecentralpressureis330billionatmosphericpressure.About15,000,000K,whichconcentrateshalfofthemassofthesunandproducesabout99%oftheenergyemittedbythesun.Becauseofthehightemperature,itssubstancesareinthegaseousstate,andtheenergyreleasedbythesolarnucleusisproducedbythefusionofhydrogenatomsintohelium.Everysecond,600milliontonsofhydrogen,whichistransformedinto596milliontonsofheliumthroughthermonuclearfusionreaction,releasestheenergyequivalentto4milliontonsofhydrogen,whichisthesourceofsolarlight.EstimatesofhydrogencontentinthesunsuggestthatthesuncanprovideatleastfivebillionyearsoflightandheattotheEarth.
　　Sincethereissomuchpressureinthecenterofthesun,whydidn'tablackholeform?Thisisbecauseparticlesinnaturecanwithstandthecontractionpressurefromthesunbymeansoftheirowngravitationalstructure,sothepressureofthesunisnotenoughtocrushthegravitationalsupportstructureofparticles,themorecompactthepressureis.Butitisbynomeansinfinitelycompressed.Whenacertaincriticalstateisreached,thegravitationalsupportstructurewillchangelocallyandformablackholeinnature.ThisaveragevaluationisgivenbyOppenheimer.ItiscalledOppenheimerlimitTOVlimit.Thecorrespondingblackholeiscalledanaturalblackhole.
　　Oppenheimer,J.R.(J.RobertOppenheimer)(19041967),Americantheoreticalphysicistandscientificorganizer,chieftechnicaldirectoroftheManhattanProjectforthedevelopmentofthefirstatomicbombsintheUnitedStates.
　　In1936,Oppenheimeretal.firstdiscussedtheequilibriumandstabilityofdensestarscomposedofdegenerateneutronmatter,i.e.neutronstars.Thepropertiesofsuchstarsaremainlydeterminedbythebalancebetweenselfgravitationanddegenerateneutronpressure.UsingthestructureequationofnonrotatingsphericallysymmetricstarsingeneralrelativityandtheidealFermigasequationastheequationofstateofneutronmatter,OppenheimeretalprovedthatthereexistsacriticalmassM_0.75M,Mrepresentingthemassofthesun.WhenthemassofastarislessthanM,thereexistsastableequilibriumsolution;onthecontrary,thereisnostableequilibriumsolution.TheuppermasslimitMofneutronstarsistheOppenheimerlimit.Iftheneutronequationofstateismoreclosetotheactualone.ThevalueofOppenheimerlimitwillbedifferentfromtheoriginalvalue.Atpresent,theequationofstateforneutronstarswithdensitiesgreaterthan10g/cmisuncertain,andtheuppermasslimitforneutronstarsisuncertain.Generally,itcanbetakenas2M.
　　TheOppenheimerLimit(TOVLimit,alsoknownasOppenheimerVolkovLimit)istheuppermasslimitforneutronstars,similartotheChandrasekaLimitforwhitedwarfstars.Asmentionedintheprevioussection,OppenheimerandVolkov'suppermasslimitforneutronstarsisabout0.7timesthemassofthesun,whichshouldbewrongtoday.Today'sresultsrangefrom1.5to3timesthemassofthesun.Forneutronstarswhosemassislessthanthislimit,theinternalpressureofsupportingstarscomesfromthestronginteractionbetweenneutronsandneutronsandthequantumdegeneratepressureofneutronsthemselves;forneutronstarswhosemassisgreaterthanthislimit,theycollapseintoablackholeundertheactionoftheirowngravitation,andmaytheoreticallybecomeotherformsofstarsunderthesupportofinternalpressureinotherways.(Forexample,itcollapsesintoaquarkstarunderthesupportofquarkdegeneratepressure).However,becausethesetheoreticalquarkdegeneratematerialsarelessknownthanneutrondegeneratematerials,astrophysicistsgenerallybelievethatneutronstarswillcollapseintoblackholeswhentheyexceedthislimitunlessthereareexamplesofactualobservations.
