石陨石 meteoric stone; meteorolite; aerolite; stony meteorite; brontolith; 中国吉林陨石雨一号是世界最大的石陨石。这块大陨石于1976年3 月8日陨落在吉林市郊区,重1,770公斤,大大超过曾一度被称为世界石陨石之冠的、现保存在美国的那块1,078公斤的石陨石。 china's jilin no.1 meteorite shower is the largest stony meteorite in the world. it fell on the suburbs of a city in jilin province on march 8, 1976. it weighs 1,770 kilograms, heavier than the one stored in the united states, which weights 1,078 kilograms and was once regarded as the largest in the world
铁陨石 siderolite; iron meteorite; aerosiderite; palasite
It seems unlikely that this abundance would have been sufficient to cause all the heating observed in meteorites 这个含量不大可能造成在陨石中观察到的受热现象。
To reach back , you need to look in the dust grains in chondrites , rather than at the chondrules 如果是追溯太阳系形成之前,你需要研究球粒状陨石中的灰尘颗粒,而不是陨石球粒。
Certain types of ancient interstellar dust ? older than the solar system ( about 4 . 6 billion years ) ? have been isolated from meteorites and analyzed 一些类型的古老星际尘埃? ?比太阳系(大约46亿年)还要早? ?已经从陨石中分离出来并分析过了。
One of these martian meteorites was once thought to harbour signs of life , in the form of carbon - containing compounds and objects that the eye of faith interpreted as fossil bacteria 这些火星陨石中曾有一个被视作生命的港湾,因为其中含碳化合物和被解释为细菌化石的物质。
Xenon is extremely rare , which allows scientists to use it to detect and trace nuclear reactions , even those that occurred in primitive meteorites before the solar system came into existence 氙非常稀有,因此科学家能利用它来侦测及追踪核反应,即使是那些早在太阳系形成之前、发生在原始陨石中的核反应。

And investigators knew that at least small amounts of compounds that can give rise to membranes are created in space : carbon - rich compounds extracted from a meteorite that fell in australia in 1969 spontaneously formed vesicles when the compounds were dissolved in water 研究者们知道至少少量能形成膜的化合物是在宇宙中形成的:从1969年坠落在澳大利亚的陨石中提取的富碳化合物在水分解时会自然地释放出小泡泡来。
