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“孔球陨石”的行星尘埃颗（IDPs）到了较的半挥素。

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.

如果你查看我们测定的素比率，你将得出结论——我们的彗星颗看上去更接近孔球陨石IDPs而不是CI球陨石。
