【摘要】：月壤中普遍存在着大量由太空风化作用产生的纳米金属铁,这些纳米金属铁在一定程度上改变了月球表面的物理、化学和光学特征。纳米金属铁在月壤中主要赋存于胶结质玻璃相中和月壤颗粒的表面,胶结质玻璃相的纳米金属铁起源于微陨石轰击富含太阳风氢粒子的月壤产生的高温熔融还原作用,颗粒表面的纳米金属铁来自微陨石轰击引起的蒸发沉积作用和太阳风、宇宙射线粒子的溅射沉积作用的共同作用。根据月壤中纳米金属铁的成因和特征,分析了采用微波加热技术和磁控溅射技术分别模拟胶结质玻璃相中和颗粒表面纳米金属铁的可行性研究,初步的模拟实验表明这两种方法模拟生产的样品中纳米金属铁的特征和真实月壤的相近,模拟样品对于月球遥感光谱解译、月球科学研究和月球探测工程都具有重要的意义。
[Abstract]:There are a lot of nanometallic iron produced by space weathering in lunar soil. To some extent, these nanometallic iron have changed the physical, chemical and optical characteristics of the lunar surface. Nanometallic iron mainly occurs in the cemented glass phase and the surface of the lunar soil particles in the lunar soil. The nano-metallic iron of the cemented glass phase originates from the melting reduction at high temperature caused by the bombardment of micrometeorites on the lunar soil rich in solar wind hydrogen particles. The nanometallic iron on the surface of particles is derived from the evaporation deposition caused by the bombardment of micrometeorites and the sputtering deposition of solar wind and cosmic ray particles. According to the origin and characteristics of nanometallic iron in lunar soil, the feasibility of microwave heating and magnetron sputtering to simulate nano-metallic iron on the surface of cemented glass phase and particle respectively was analyzed. The preliminary simulation experiments show that the characteristics of the nanometallic iron in the samples produced by these two methods are similar to those of the real lunar soil, and the simulated samples are of great significance for the interpretation of the remote sensing spectrum of the moon, the scientific research of the moon and the exploration of the moon.
