1. Some people have reported seeing more semivolatile elements in a class of interplanetary dust particles (IDPs) called "chondritic porous" IDPs. 曾有人报告在一类被称作“多孔球粒陨石”的行星尘埃颗粒(IDPs)中见到了较多的半挥发性元素。
2. If you look over the element ratios we measured, you might conclude that our comet particles look more like chondritic porous IDPs than CI chondrite meteorites. 如果你查看我们测定的元素比率,你将得出结论——我们的彗星颗粒看上去更接近多孔球粒陨石IDPs而不是CI球粒陨石。
3. Because the chondritic asteroids formed after the chondrules did, the initial 26Al to 27Al ratio in chondrules places an upper limit on the amount of 26Al that was available to heat the rocky bodies. 因为球粒陨石小行星是在球粒之后形成,球粒中铝26对铝27的初始比值,决定了能够用来加热石质天体的铝26含量的上限。
