„Professor, should our bodies not carry the microorganism on meteorite? I have not touched that meteorite.” “教授,我们身上应该不会携带陨石上的微生物吧？我都没碰过那陨石。” Niu Dazhi stroked gently clothes on lower part of the body with the hand, there are already the unclean misconception. 牛大志用手摩挲了一下身上的衣服,有一种自己已经不干净的错觉。 Lu Xiuwen tone amiable saying: „ Do not be anxious, asking you to come back to take the examination, but to guarantee the microorganism in meteorite has not proliferated. 鲁修文语气随和的说道:“别紧张,叫你们回来做检测,只是为了确保陨石中的微生物没有扩散出去。 „Theoretically, your bodies should not contaminate these microorganism, the examination is also only the routine business.” “理论上来说,你们身上应该是没有沾染到这些微生物的,检测也只是例行公事。” Several people of speaking times, the astronomy professor of space technology university leads two graduate students to come, communicates with Lu Xiuwen. 几人正说话的时候,航天科技大学的一名天文学教授带着两名研究生过来,和鲁修文进行沟通。 Because this meteorite came from the outer space, therefore related to astronomy domain. 由于这颗陨石来自外太空,所以涉及到了天文学领域。 „Professor Lu, this is the precept of headquarters, I am responsible to this meteorite conduct the research in astronomy.” The astronomy professor of space technology university goes forward with the Lu Xiuwen handshake. “鲁教授,这是总部的命令状,我负责对这块陨石进行天文学方面的研究。”航天科技大学的天文学教授上前和鲁修文握手。 „Hello, welcome, Professor Lang, first please sit down, first please sit down.” Lu Xiuwen and he shakes hand, while asked him to sit down. “你好你好,欢迎欢迎,郎教授,先请坐,先请坐。”鲁修文一边和他握手,一边请他坐下。 This astronomy professor named Lang Tongguang, domestic astronomy circle, is the pivotal character. 这位天文学教授名叫郎同光,在国内的天文学界,也是举足轻重的人物。 Appearance as a result of Star Beast world, therefore in recent decades, the astronomy was popular. 由于星兽世界的出现,所以最近几十年,天文学一直是热门。 Fang Yuan felt that this Professor Lang Tongguang a little looks familiar, has probably seen in the television news. 方源感觉这位郎同光教授有点眼熟,好像是在电视新闻里见到过。 After two people smalltalk ends, Lang Tongguang then direct examination: „When can I see that meteorite?” 两人客套完之后,郎同光便直接询问:“我什么时候能见见那块陨石？” „We are doing the protection work of microorganism, after can protect the work to complete, can look. Also takes about an hour probably, can Professor Lang wait?” Lu Xiuwen looked at time on wrist watch. “我们正在做微生物的防护工作,能防护工作完成之后,就可以去看。大概还要一个小时左右,郎教授能等吗？”鲁修文看了一下腕表上的时间。 One hour is not long, Lang Tongguang is also knew that in the meteorite discovered the microorganism, applied to come to the headquarters, he knows that the microorganism in this meteorite possibly came from other stars, this regarding the astronomy, has the important research value. 一个小时不算长,郎同光也是得知陨石中发现了微生物,才向总部申请过来的,他知道这颗陨石里的微生物可能来自其他星球,这对于天文学来说,有着重要的研究价值。 Then. 接下来。 The Code Shenzhou aircraft crew conducted the examination of microorganism one after another, after confirming does not have the issue, then allowed to go home respectively. 神舟号的机组人员陆续进行了微生物的检测,确认没有问题之后,便允许各自回家。 Fang Yuan several people have not walked, saw that Lu Xiuwen and Lang Tongguang are discussing the matter about meteorite, then collects to audit. 方源几人并没有走,见到鲁修文和郎同光正在探讨关于陨石的事情,便凑过去旁听。 Probably after over the past hour, a researcher walks, reported to Lu Xiuwen: „Professor, the protection work was completed.” 大概过去一个小时之后,一名研究员走过来,向鲁修文报告道:“教授,防护工作完成了。” „That whether to look at the meteorite?” Lang Tongguang is somewhat impatient. “那是不是可以去看陨石了？”郎同光有些心急。 This has the meteorite of microorganism after all together, may be from another star that has the life, this regarding the research of astronomy, is a major breakthrough. 这毕竟是一块存在微生物的陨石,极有可能是来自另外一个存在生命的星球,这对于天文学的研究来说,是一个重大的突破。 Before then, Human once in several hundred thousand years ago meteorites, discovered the fossil of microorganism, but never has the microorganism that the discovery earns a living. 在此之前,人类曾经在几十万年前的陨石中,发现微生物的化石,但从来没有发现过活的微生物。 This time, really discovered in the meteorite live microorganism, the exciting mood in Lang Tongguang heart is beyond description. 这一次,是真的在陨石中发现了活的微生物,郎同光心中的激动情绪是难以形容。 Fang Yuan several people also follow to look at the meteorite. 方源几人也跟着去看陨石。 The group arrive to deposit the meteorite laboratory, after wearing the exposure suit, walks, the short distance watches that meteorite. 一行人走到存放陨石的实验室,穿上防护服之后,才走进去,近距离观看那块陨石。 Meteorite that meteorite. 陨石还是那块陨石。 Fang Yuan has not only looked, but also has traced. 方源不仅看过,还摸过。 However, now sees this meteorite again time, the feeling is completely different. 不过,现在再次看到这块陨石的时候,感觉完全不一样。 The shape has not changed, but the first seeing time, does not know that in it has the microorganism. 形状没有发生变化,但是第一次见到的时候,并不知道它里面存在微生物。 Now, sees this meteorite again time, knows microorganism that in it has possibly came from the extraterrestrial, this feeling is very subtle. 现在,再看到这块陨石的时候,知道了它里面存在着可能来自外星的微生物,这种感觉很微妙。 This meteorite is very big, the diameter about five meters, assume the irregular shape. 这块陨石很大,直径五米左右,呈不规则形状。 The naked eye seems like, this meteorite is together the mineral content high stone, and has no special place. 肉眼看上去,这块陨石就是一块矿物质含量较高的石头,并没有什么特殊的地方。 From the elementary analysis, the principal element is the iron and silicon, has no extraordinary place. 从元素分析来看,主要元素是铁和硅,也没有什么出奇的地方。 „Professor Lang, is the microorganism on this meteorite really the alien?” Eve curious about sizes up, asked an issue. “郎教授,这块陨石上的微生物真的是外星生物吗？”伊芙好奇的上下打量,提出了一个问题。 „Is unascertainable. However, this star/celestial body should not call the meteorite actually, according to checking material, it is actually a asteroid.” Lang Tongguang investigates the correct path. “还不能确定。不过,这块星体其实不应该叫陨石,根据查到的资料,它其实是一颗小行星。”郎同光纠正道。 „Planetoid? Can five meters also calculate the asteroid?” The people are somewhat accidental. “小行星？五米也能算小行星吗？”众人有些意外。 Because of this stone, if regarded as the meteorite, that is big, but if treats as the asteroid, that was also too small. 因为这块石头,如果当做是陨石的话,那算是大的,但如果当做小行星的话,那也太小了。 „Yes, according to the regular diameter over three meters of asteroid, below 300 kilometers star/celestial body, calls it the asteroid. Although this star/celestial body is small, but it truly conforms to the standard of asteroid.” Lang Tongguang confirmed. “是的,按照小行星的规则直径三米以上,三百公里以下的星体,都称之为小行星。这块星体虽然小,但它确实符合小行星的标准。”郎同光确认道。 Fang Yuan blinks the eye, said: „You meant, this stone does operate around Sun?” 方源眨巴一下眼睛,道:“你的意思是说,这块石头是围绕太阳运行的？” „Yes, this asteroid is the near-earth asteroid, although small size, but because the track has one to be away from Earth to be very near, therefore Human has actually discovered it......” “是的,这颗小行星属于近地小行星,虽然体积小,但由于轨道有一段距离地球很近,所以人类其实已经发现它……” Lang Tongguang starts in astronomy, explained: „ If this asteroid had not been brought by you, it circles Sun to operate every time for a week, when close to Earth, by the attractive effect of Earth, being enabled the orbit to have the deflection of small angle, in the future will exist to run upon the possibility of Earth. 郎同光开始在天文学方面,进行解释:“如果这颗小行星没有被你们带回来的话,它每绕太阳运行一周,在靠近地球的时候,都会被地球的引力影响,使得运行轨道发生小角度的偏转,未来存在撞上地球的可能。 „ But, because this asteroid is too small, even if crashes into Earth, will not cause the disaster, therefore the astronomy circle has not sounded the early warning. “不过,由于这颗小行星实在太小,即便坠入地球,也不会引发灾难,所以天文学界并没有发出预警。 „ In fact, like this five meters to ten meters asteroid, average one year will present an atmosphere that enters Earth. “事实上,像这种五米到十米的小行星,平均一年就会出现一颗进入地球的大气层。 „The energy of release is equivalent to an equivalent of atomic bomb probably, but most parts branch gasifies in the atmosphere, will therefore not have the too tremendous impact on Earth.” “释放的能量大概相当于一颗原子弹的当量,不过大部分会在大气层中气化,所以并不会对地球造成太大的影响。” Several people have not thought, a stone of such five meters diameter, can be a asteroid unexpectedly, somewhat is surprised. 几人都没想到,这么一块五米直径的石头,竟然会是一颗小行星,都有些惊讶。 Fang Yuan curious questioning: „Then must the big asteroid crash into Earth, will cause the disaster?” 方源好奇的追问:“那么要多大的小行星坠入地球,才会引发灾难？” „About 50 meters in diameter asteroid average in 1000 hit Earth one time, the produced explosion was equivalent to the early 20 th century page the Tunguska event. This magnitude asteroid hits Earth, Earth can withstand, over 100 meters issue will not be serious. If the diameter of asteroid is one kilometer, that will cause the destructive disaster.” Lang Tongguang patient explanation several people of issues. “直径约50米的小行星平均一千年撞击地球一次,产生的爆炸相当于20世纪初页的通古斯大爆炸。这个数量级的小行星撞击地球,地球还是能承受的,超过一百米问题也不会太严重。如果小行星的直径达到一千米,那将会引发毁灭性的灾难。”郎同光耐心的解答几人的问题。 „Are many like the asteroid?” Fang Yuan pursues asks. “像这样的小行星很多吗？”方源追问道。 „At present, Human in the asteroid quantity in the Solar System discovering, the named asteroid is 120,000.” “目前,人类在太阳系中发现的小行星数量,已经命名的小行星则是12万。” Lang Tongguang continues the popular science: „ But, the orbits of overwhelming majority asteroids, between tracks of sparks/Mars and Jupiter. Also is majority in the asteroid belt/bring. 郎同光继续科普:“不过,绝大部分的小行星的运行轨道,都在火星和木星的轨道之间。也就是大部分都在小行星带中。 „ The track of asteroid belt/bring, at tracks of sparks/Mars and between Jupiter. “小行星带的轨道,处在火星和木星的轨道之间。 „ In the Solar System, the planet closest to sun is Mercury, next is Venus, is Earth. “在太阳系里,距离太阳最近的行星是水星,其次是金星,然后就是地球。 „sparks/Mars in the outer ring of earth's orbit, beside the Mars orbit, is the asteroid belt/bring, is Jupiter.” “火星在地球轨道的外圈,火星轨道之外,就是小行星带,然后就是木星。”
