模拟月壤研制的初步设想

A Review and Prospect for Developing of Lunar Soil Simulants

模拟月壤是月球样品的地球化学复制品．作者总结世界上已有的5种模拟月壤 JSC-1，MLS-1，MLS-2，MKS-1和 FJS-1的研制过程、方法与基本理化性质．认为系列化模拟月壤研制对中国首次月球探测有重要意义．在此基础上，作者提出系列化模拟月壤研制的基本思路．

Lunar soil simulants are geochemical copycats of lunar sample.They have similar chemi-cal composition,mineralogy,particle size distribution,and engineering properties with lunar sample.Simulants of lunar rocks and soils have been developed to satisfy the requirements of a variety ofscientific and engineering investigations.They are essential to meet the system requirements forlunar exploration and in support of future human activities on the Moon.Such studies include ma-terial handling,construction,excavation,and transportation.The simulants is also appropriate forresearch on dust control,spacesuit durability,and agriculture.Five lunar soil simulants,JSC-1,MLS-1,MLS-2,MKS-1,FJS-1 are reviewed in the paper.Theirstarting materials,preparation,and characterization(chemical composition,mineralogy,particle sizedistribution,specific gravity,angle of internal friction,and cohesion)are also listed.China will realize the first lunar exploration before 2007.So it is an essential and pressing taskto develop lunar soil simulants series corresponding to average chemical and mineral composition oflunar sample at Apollo and Luna landing sites.The tentative ideas of developing new lunar simuantsseries based on geologic investigations were brought forward in the end.
