1.Some people have reported seeing more semivolatile elements in a class of interplanetary dust particles (IDPs) called “chondritic porous” IDPs.

1.曾有人报告在一类被称作“孔球粒陨石”行星尘埃颗粒（IDPs）中见发性元素。

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.

2.如果你查看我们测定元素比率，你将得出结论——我们彗星颗粒看上去更接近孔球粒陨石IDPs而不是CI球粒陨石。
