天舟一号Tianzhou-1Chinahastakenanothersteptowarditsgoalofputtingaspacestationintoorbitaround2022,bysendingitsfirstcargospacecraftTianzhou-1intospaceonThursdayevening.我国首个货运飞船天舟一号于20日晚发射升空,我们朝着2022年前后建立轨道空间站的目标又迈进了一步.AtopaLongMarch-7Y2carrierrocket,Tianzhou-1roseintotheairfromtheWenchangSpaceLaunchCenterinsouthChinasHainanProvinceat7:月20日19时41分,搭载着天舟一号货运飞船的长征七号遥二运载火箭,在我国文昌航天发射场点火发射.天舟一号(Tianzhou-1)是我国自主研制的首艘货运飞船(thefirstcargospacecraftdevelopedbyChina),也是中国目前为止体积最大、重量最重的航天器(thelargestandheaviestspacecraft).由于它只运货,不送人,所以被形象地称为太空"快递小哥"(spacecourier/deliveryman).天舟一号采用两舱式结构,直径较小的是推进舱(propellingmodule),直径较大的为货物舱(cargomodule).飞船全长米,最大直径米,起飞质量(takeoffweight)约13吨,太阳帆板展开后最大宽度米,物资运输能力(payloadcapacity)约吨,推进剂补加能力约为2吨.Tianzhou-1smostcapablecargospacecraftinservice:JapansH-IITransferVehiclehas6tonsofpayloadcapacity;theCygnusandDragon,bothUS-madecraft,;andRussia天舟一号吨的物资运输能力使其成为世界上运输能力最强的现役货运飞船:日本的H-II货运飞船运输能力为6吨;美国的"天鹅座"和"龙"飞船的运输能力分别为吨和吨;俄罗斯的进步-MS飞船为吨.天舟一号在太空要执行哪些任务?飞船入轨后,将按预定程序与在轨运行的天宫二号先后进行自动交会对接(autonomousdocking)、自主快速交会对接(autonomousfastdocking)等3次交会对接,3次推进剂在轨补加(propellantin-orbitrefueling)以及空间应用和航天技术等领域的多项实(试)验.首次对接:两天后,天舟一号与天宫二号进行首次交会对接.之后,天舟一号与天宫二号组合体将进行为期两个月的在轨飞行.期间,计划完成3次推进剂在轨补加试验(experimentsonpropellantin-orbitrefueling),同时测试货运飞船对组合体的控制能力(testthecontrollingabilityofthecargospacecraftoverthetwospacecraft).二次对接:完成首次对接后,天舟一号与天宫二号分离,然后绕飞到天宫二号的另一侧,进行第二次对接.第二次对接的主要任务是进行绕飞实验(fly-aroundtests),检验天舟一号前向对接能力(capabilityofforwarddocking).之后天舟一号与天宫二号再次分离,两个飞行器将独立飞行三个月,完成搭载的空间科学试验(spacescientificexperiments).三次对接:天舟一号与天宫二号进行最后一次对接,验证自主快速交会对接(autonomousfastdocking)技术,要求在六小时左右实现对接.完成所有既定任务后,天舟一号将受控离轨,陨落至空间安全海域(fallintoadesignatedseaarea).此次任务是中国载人航天工程空间实验室阶段(spacelaboratorystageofChinamannedspaceengineering)的收官之战,对于空间站工程后续任务顺利实施具有极为重要的意义,将标志着中国载人航天工程胜利完成"三步走"战略中的"第二步"任务,为空间站建设任务奠定坚实技术基础.1992年9月,中国实施载人航天工程并确定中国载人航天"三步走"的发展战略(three-stepmannedspaceprogram):第一步,发射载人飞船(mannedspaceship),建成初步配套的试验性载人飞船工程,开展空间应用实验.2013年神舟5号载人飞船任务顺利完成.第二步,突破航天员出舱活动技术(extra-vehicularactivity)、空间飞行器的交会对接技术(rendezvousanddocking),发射空间实验室(spacelab),解决有一定规模的、短期有人照料的空间应用问题.第三步,建造空间站,解决有较大规模的、长期有人照料的空间应用问题(operateapermanentmannedspacestation).

脉冲星pulsar10月10日,中国科学院国家天文台宣布,500米口径球面射电望远镜(FAST)经过一年调试,已实现指向、跟踪、漂移扫描等多种观测模式的顺利运行,并确认多颗新发现脉冲星.Afteroneyearoftrialoperation,ChinasFive-hundred-meterApertureSphericalRadioTelescope(FAST),theworldslargestsingle-dishradiotelescope,hasidentifiedmultiplepulsars,theNationalAstronomicalObservatoriesofChina(NAOC)月10日,中国科学院国家天文台宣布,经过一年调试,500米口径球面射电望远镜(FAST)已发现多颗脉冲星.FAST是世界上最大的单口径射点望远镜.Twoofthepulsars,namedJ1859-01andJ1931-01,are16,000lightyearsand4,,respectively.新发现的脉冲星中有两颗分别为J1859-01和J1931-01,前者距离地球万光年,自转周期秒,后者距离地球4100光年,自转周期秒.据科学家介绍,脉冲星(pulsar)是一种高速自转的中子星(neutronstar),由恒星演化和超新星爆发产生.它的密度极高(superdensity),每立方厘米重达上亿吨,一块方糖大小就相当于地球上一万艘万吨巨轮的重量.脉冲星自转速度很快(fastrotationalspeed)、自转周期精确(accuraterotationperiod),是宇宙中最精准的时钟.这一特殊"本领",让脉冲星在计时、引力波探测(findinggravitationalwaves)、航天器导航(navigatingspacecraft)等领域具有重要应用.这两颗脉冲星J1859-01和J1931-01分别由"中国天眼"于今年8月22日、25日在南天银道面(thesoutherngalacticplane)通过漂移扫描(drift-scanning)发现.目前"天眼"已探测到数十个优质脉冲星候选体(promisingpulsarcandidates),其中6颗通过国际认证.对于观测范围可达已知宇宙边缘的"天眼"来说,发现脉冲星只是使命之一,未来,它还将在中性氢观测(neutralhydrogenobservation)、谱线观测(spectrumobservation)、寻找可能的星际通讯信号(explorationofinterstellarcommunicationsignals)等方面大放异彩.2016年9月25日,我国500米口径球面射电望远镜(FAST)正式落成启用,位于贵州省平塘县名为大窝凼的喀斯特洼地(naturallydeepandroundkarstdepression)之中.其接收面积(receivingarea)相当于30个足球场大鞘澜缱畲蟮牡タ诰渡涞缤毒射电望远镜(radiotelescope)接收的是肉眼看不到的射电波(radiowaves),跟接收卫星信号的天线锅类似,通过锅的反射聚焦,把几平方米到几千平方米的信号聚拢到一点上.因此,FAST的工作不是"看",而是"听",依靠500米口径的"大耳朵"来"收听"太空深处物体发出的无线电波.,ag环亚线上网址区块链blockchainBlockchainisanewcomputertechnologythatcombinestheapplicationofdistributeddatastorage,point-to-pointtransmission,encryptionalgorithmandotheradvancedtechnologies,rencybitcoin,whereitservesasthepublicledgerforalltransactionsonthenetwork.区块链技术是利用块链式数据结构来验证与存储数据、利用分布式节点共识算法来生成和更新数据、利用密码学的方式保证数据传输和访问的安全、利用由自动化脚本代码组成的智能合约来编程和操作数据的一种全新的分布式基础架构与计算范式.区块链的概念在2008年被提及,在随后的几年中,成为了电子货币比特币的核心组成部分,既作为所有交易的公共账簿.Relatednews:。GeneralSecretaryoftheCentralCommitteeoftheCommunistPartyofChina(CPC)andChinesePresidentXiJinpingandhiswifePengLiyuanattendaseeing-offceremonyheldbyKimJongUn,chairmanoftheWorkersPartyofKorea(WPK)andchairmanoftheStateAffairsCommissionoftheDemocraticPeoplesRepublicofKorea(DPRK),andhiswifeRiSolJu,aheadoftheirdepartureattheairportinPyongyang,capitaloftheDPRK,June21,(Xinhua/HuangJingwen)PYONGYANG,June21(Xinhua)--ChinesePresidentXiJinpingstwo-daystatevisittotheDemocraticPeoplesRepublicofKorea(DPRK)isamajordiplomaticactionthatcomesastheworldisundergoingchangesunseeninacenturyandtheinternationalsituationisseeingcomplexandprofoundchanges,,headoftheInternationalDepartmentoftheCentralCommitteeoftheCommunistPartyofChina(CPC),thevisit,whichcoincideswiththe70thanniversaryofthediplomatictiesbetweenChinaandtheDPRK,isalsoXisfirsttriptotheneighboringcountrysincehebecametheChinesepresidentandgeneralsecretaryoftheCentralCommitteeoftheCPC,rtancetoXisvisitandreceivedtheChineseleaderwithgrandandwarmwelcome,Songnoted,sayingthatKimJongUn,chairmanoftheWorkersPartyofKoreaandchairmanoftheStateAffairsCommissionoftheDPRK,andhiswife,RiSolJu,welcomedXiandhiswife,PengLiyuan,attheairport,,frankandin-depthexchanges,andhavereachedkeyconsensusonwritingnewchaptersfortheChina-DPRKfriendship,andsafeguardingpeaceandstabilityintheKoreanPeninsula,,Xihasengagedaseriesofexchangeswithofficialsandordinarypeopleinthecountry,whilehundredsofthousandsofresidentsinPyong,arty,governmentandpeopleoftheDPRKtowardstheparty,governmentandpeopleofChina,svisitwasavisitoffriendshipandpeace,andhasdisplayedChinasdeterminationtostaycommittedtoconsolidatingthetraditionalChina-DPRKfriendship,supportingtheimplementationofDPRKsnewstrategiclineandprosteredbytheireldergenerationofleaders,andthetopleadersofthetwosideshavemaintainedatraditiontokeepaclosecontact,strip,saidSong,hasrealizednotonlythehistoricalexchangeofvisitsbythetopleadersofthetwopartiesandcountriesinsuchanimportantyearastheonethatmarksthe70thanniversaryofthediplomatictiesbetweenChinaandtheDPRK,butalsothe5thgatheringbetweenthemin15months,addingthatitwillbeamuch-toldstoryinthetwocountries,XiandKimhaveconductedin-depthexchangesonfurtheringthedevelopmentoftheChina-DPRKrelationship,andhavereachedextensivemajorconsensus,whichhelpsdrawablueprintforthefutureofbilateralties,teredanewhistoricalera,addingthattheCPCandtheChinesegovernmentwillstayfirmlycommittedtomaintaining,consolidatingandnurturingthebilateralties,andChinaiswirty,governmentandpeopleoftheDPRKandhasshowntheworldtheunbreakableChina-DPRKfriendship,addingthatbothsideshaveagreedthattheywillstepuphigh-levelexchangesandstrategiccommunicationsoastopromoteanevengreaterachievementinthetradi,thetwoleadersexchangedin-depthviewsonthesocialistconstructionoftheirrespectivecountries,saidSong,addingthatXispokehighlyoftheposathinlinewithitsnationalconditions,addingthatChinastandsreadytodeepenexchangesandmutuallearningwiththeDPRKonpartyandstategover,notingthattheChineseleaderscloseattentiontotheDPRKssocialistconstructionaswellasitsdevelopmentineconomyandlivelihoodhasstrengthenedtheconfidenceofthepartyandpeopleoftheDPRKintheircause,,Songsaid,jointlyblueprintedindetaila
