又考到关于那个regolith，这里是重点好好看。。问这个agglutinates有什么特点。。我好像选的是被GLASS包围的那一项。。还有什么IRON含量很高，或者是来自regolith。。
Tothe naked eye, lunar soillooks rather ordinary, just a dark grey powder. You might think you could scoop up somethinglike it on a black-sand beach in Hawaii. But moon dust is quite literally out of this world. Amicroscopic view reveals a mixture of basalt fragments, beautiful round beadsof volcanic glass, sharpfragments of broken glass and complicated particles called agglutinates, whichconsist of pieces of rock or mineral welded together by glass. The variety ofparticles is a testament to the moon’s 4 billion years of pummelling bymeteorites.

At the Huntsville workshop, researchers agreed that at least two and perhaps three “root” simulants would be needed this time. One, a clone of JSC-1, would mimic the basaltic composition of the moon’s maria – flat plains once thought to be seas – while the second would replicate the more aluminium-rich regolith of the highland regions. A third might be developed to represent the soil in the permanently shaded regions near the moon’s poles, which may contain small amounts of water ice. “If we had these root simulants and worked only with them, at least everyone would have a common starting point,” says Taylor. He emphasises that “one simulant does not fit all”. Researchers would have to make modifications to study some of the more exotic properties of moon dust – and there are plenty of those.
