refractory inclusion meaning in Chinese
耐火材料夹杂物
Examples
- The minerals in these assemblages form at high temperatures , at least 1 , 180 degrees c , so the refractory inclusions presumably date from the very beginning of the solar system ' s history , before the solar nebula cooled significantly
这些组合体内的矿物形成于非常高的温度，至少约1180 ，因此耐火包体可能产生于太阳系历史的最初期，在太阳星云显著冷却之前。 - These investigations have found strong evidence for the former presence of 26al in the so - called refractory inclusions : tiny mineral assemblages , rich in calcium and aluminum , embedded in chondritic meteorites alongside the chondrules
这些研究发现了强而有力的证据，显示铝26曾经存在于所谓的耐火包体（富含钙和铝的细小矿物组合体，与球粒一起镶埋在球粒陨石内） 。 - Given the decay rate of 26al , the lower initial ratio in the chondrules implies that these objects formed between one million and two million years after the creation of the refractory inclusions ( assuming that the radioisotope was indeed homogeneously distributed in the early solar system )
以铝26的衰变速率估计，这些球粒的初始比值较低，表示它们是在耐火包体产生后100 ~ 200万年才形成（假设铝26在早期太阳系中确实是均匀分布的） 。 - To circumvent this problem , advocates of 26al heating hypothesize that some chondrules might have formed earlier in the solar system ' s history ? perhaps closer to the time when the minerals in the refractory inclusions condensed from the solar nebula ? and thus had much higher 26al to 27al ratios
为了解决这个问题，铝26加热说的拥护者假设，某些球粒可能是在太阳系历史的更早期形成，也许与耐火包体开始由太阳系星云的收缩而形成的时间差不多，因此铝26对铝27的比值较高。
