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“孔球”的行星尘埃颗（IDPs）中见到了较的半挥发性元素。

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.

如果你查看定的元素比率，你将得出结论——的彗星颗看上去更接近孔球IDPs而不是CI球。
