关于小行星中的水泥的说明
A note on cement in asteroids
摘要：
雪硅钙石是碳质球粒陨石中富钙铝包裹体（CAIs）在热液作用下形成的胶结矿物。在14微米处的不明波段被测量为CAIs和Allenium陨石样本的基质，以及Hektor和Agamemnon小行星。水泥纳米颗粒的存在可以解释14微米处的特征。
英文摘要：
Cement mineral tobermorite was formed in hydrothermal experiments on alternation of calcium-aluminum-rich inclusions (CAIs) in carbonaceous chondrite meteorites. Unidentified bands at 14 microns were measured for CAIs and the matrix of the Allende meteorite sample, as well as for Hektor and Agamemnon asteroids. The presence of cement nanoparticles may explain the feature at 14 microns.
