以下为句子列表:
英文: Even after making generous assumptions, we determined that the maximum temperature reached in carbonaceous-chondrite asteroids with a diameter of 80 kilometers or more would be only 670 degrees C, too low to cause any melting at all.
中文: 即使给予很宽松的假设,我们认为直径在80公里或以上的碳质球粒陨石小行星,达到的最高温度只有670℃,不足以造成任何的熔化。

英文: The average composition for our sample is different in some ways from the CI chondrite meteorites: namely we found more zinc, gallium, and copper, and less sulfur.
中文: 我们样品的平均成分水平在某些方面与CI球粒陨石不同:即我们发现有较多的锌、镓和铜及较少的硫。

英文: Thermal models show that even if the asteroids assembled immediately after the formation of the chondrules, 26Al heating would have raised temperatures in the interiors of ordinary-chondrite bodies to a maximum of 1,100 degrees C—high enough to cause melt
中文: 热模型显示,即使小行星在球粒形成之后立刻聚合,铝26的加热最多也只能将普通球粒陨石内的温度提高到1100℃,虽可使金属和硫化物熔化,但并不足以将矽酸盐矿物大量熔化并造成小行星各层分异。
