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元素比率，你将得出结论——我们颗看上更接近多陨石IDPs而不是CI陨石。

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“多陨石”行尘埃颗（IDPs）中见到了较多半挥发性元素。
