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 di

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）。
