■反思 S reflection

　　国防部此前收到过陨石信息 Department of defense had received meteorite information

　　据俄罗斯《消息报》网站报道，俄罗斯国防部表示，他们几天前已收到有关坠落陨石的信息，但当时专家认为这颗陨石会在坠落地球前燃烧殆尽，因此没有发出警报。据推测，这颗陨石重达10至30吨，速度达30至40公里/秒。

According to Russian[izvestia]Web site reported,The Russian defense ministry said,They have received a few days ago the meteorite fall information,But at that time the experts think this meteorite fall before the earth in burn,So there is no warning.It is assumed that,The meteorite weighed 10 to 30 tons,Speed up to 30 to forty kilometers per second.

　　另外，车里雅宾斯克动物园工作人员告诉俄新社，该动物园里的部分动物从14日夜间就开始有异常反应，其中狼和马的反应最为激烈。但目前尚不清楚动物的异常反应是否与陨石坠落有联系。

In addition,Chelyabinsk zoo workers told EXinShe,This part of the animal in the zoo from 14 night began to have abnormal reaction,The Wolf and the horse of the most violent reaction.But it is unclear whether animal abnormal reaction with meteorite fall have a contact.

　　不过，北京天文馆馆长朱进介绍说，每天有将近200块陨石落到地球表面，其中绝大多数掉进海里。1976年，中国发生“吉林陨石雨”，前两年在青海西宁附近也曾有过陨石雨。天文馆对小行星有监测系统，但对于陨石这样的流星体“完全没有可能提前知道”。

but,Beijing planetarium curator ZhuJin said,Every day there are nearly 200 meteorite fell on the surface of the earth,The vast majority of them fell into the sea.In 1976,,China has"Jilin meteorite shower",The first two years in qinghai xining nearby also had meteorite shower.The asteroid planetarium is monitoring system,But for such meteoroid meteorite"No may know ahead of time".

陨石坠落居民区并不多见 Meteorite fall residential area does not see more

　　据新华社电 15日早晨发生在俄罗斯车里雅宾斯克州的陨石坠落事件引起科学界和舆论的热议，“俄罗斯陨石”已成为目前社交网站推特上最热门的关键词之一。科学家和天文爱好者试图通过网上流传的现场视频和新闻报道中的只言片语来推测这个造访地球的“天外来客”究竟是什么。

According to xinhua 15 morning happened in Russia chelyabinsk state meteorites crash caused by the scientific community and public opinion against the heat,"Russia meteorites"Has become the current social networking websites, push on one of the key words of the most popular.Scientists and astronomical fans trying to spread through the Internet to the video and news reports of a few words to speculate that the visit of the earth"Visitors from outer space"what.

　　有天文爱好者在社交网站上说，“小行星2012DA14今晚将飞至距地球27700公里处，这一距离比地球同步卫星的轨道高度还要低，坠落俄罗斯的陨石可能是小行星靠近地球的前兆”。但俄天文学家否定了这种说法，因为陨石的飞行方向是从东北到西南，而2012DA14与前者几乎是“相向而行”。

Have enthusiast on social networking sites said,"The asteroid 2012 da14 tonight will fly to 27700 kilometers away from the earth,This distance than the earth synchronous satellite orbit altitude is still lower,The meteorite fall Russia may be asteroids closer to earth precursors".But Russia astronomers denied the claim,Because the meteorite flight direction from northeast to southwest,And 2012 da14 and the former is almost"Counter and do".

　　俄科学院地圈动态研究所研究员瓦列里·舒瓦洛夫在接受俄媒采访时猜测，拜访车里雅宾斯克州的“客人”可能是一颗重达数吨的小型陨石。此外，它可能是非常罕见的铁镍陨石，因为天体抵达大气层下层需要足够的硬度，否则会在大气层中燃烧解体。

Russian academy of sciences researcher at the institute of tile around the dynamic column, hsu tile love in an interview with Russian media speculation,Visit chelyabinsk state"The guest"May be a weigh several tons of small meteorites.In addition,It may be very rare iron nickel meteorites,Because the celestial arrived in lower atmosphere need enough hardness,Otherwise you will in the atmosphere the disintegration of combustion.

　　俄科学院天文学研究所研究员谢尔盖·巴拉巴诺夫表示，陨石坠落现象每年在地球上可观测到多次，但像这次落入居民区的情况并不多见。今天坠落的陨石发出非常耀眼的光，且带着白烟，按惯例它应该能落在地面。不过这位专家指出，陨石碎片找不到的情况时有发生。俄科学院暂无向坠落地点派遣考察组的计划。

Russian academy of sciences researcher at the institute of astronomy sergei barabbas maloof said,Meteorite fall phenomenon in every year on the earth many times can be observed,But like the fall of the residential area does not see more.Today the meteorite fall out very dazzling light,And with white smoke,Traditionally it should be able to fall on the ground.But the experts say,Meteorite fragments can't find situation happen from time to tome.Russian academy of sciences, no place to fall to send study plan.
