- 阿连德陨石中同样令人困惑的成分是那些耐高温的内部物质:往往比陨石球粒要大的不规则白色块状物。
youdao
- 2. These seeds are actually chondrules: millimeter-sized melted droplets of silicate material that were cooled into spheres of glass and crystal.

- 3. At one time it was thought that these matrix grains might be pristine nebular dust, the sort of stuff from which chondrules and inclusions were made.
- 曾经有人认为,这些基质颗粒可能是原始的星云尘埃,即形成陨石球粒及其内含物的物质。
youdao
- 4. Study of the textures of chondrules confirms that they cooled rather quickly, in times measured in minutes or hours, so the heating events that formed them must have been localized.
- 对陨石球粒质地的研究证实,它们的冷却速度相当快,短则几分钟,长则数小时,因此形成陨石球粒的高温活动肯定是局部的。
youdao
- 5. Chondrules and inclusions in Allende are held together by the chondrite matrix, a mixture of fine-grained, mostly silicate minerals that also includes grains of iron metal and iron sulfide.
- 阿伦德陨星里的陨石球粒和内含物是由球粒陨石基质结合到一起的;这是一种细粒混合物,主要包括铁颗粒和硫化铁的硅酸盐矿物。

- 球粒陨石的或与之相关的。
youdao
- 7. Work out how old the oldest chondrules are, and you know when the sun ignited.

youdao
- 8. That means they contain spherical nodules a few millimetres across, known as chondrules.
- 这意味着它们含有直径数毫米的球形岩球(或叫做陨石球粒,chondrule)。
youdao
- 9. Looking at these isotopes allows the chondrules to be dated, and they were formed 4.56 billion years ago.

youdao
- 11. First, dust particles clumped together to form cosmic dustballs. Bursts of heat from the primitive sun melted the dustballs, which solidified into chondrules.
- 从陨石推断和经过电脑软件确认可行,行星的形成过程应该如此.首先,灰尘微粒聚集在一起形成宇宙尘球.早期太阳的热量爆发将这些尘球熔化,它们因此固化为陨石球粒.
youdao
- 12. Although such hypothetical chondrules should have been preserved, researchers have not yet found any. to be fair, though, scientists have only just begun to look.
- 这种假设性的球粒应该能保存下来,但是研究人员至今仍尚未寻获(不过,公平说来,科学家也才刚开始寻找而已)。
youdao
- 13. Small asteroids are often little more than piles of dust and chondrules, the spherical pebbles of rock that formed from dust which melted in the heat of the young sun.
- 体积较小的小行星只不过是一些尘埃和陨石球粒的堆积物,其中这些圆状岩石形成于太阳早期高热量下融熔的尘埃。
youdao
