摘要: 本文从微重力定义出发,论述了微重力物理效应在流体中发生的原因,并由此把微重力物理效应分成一级和二级效应两类。建立了各类空间村料加工和微重力物理效应的联系,并分别给出发生各类微重力物理效应所需的微重力水平估算。

关键词: 材料, 空间加工, 失重环境, 估价

Abstract: In this paper,the origins of the physical effect of microgra-vity that occu in fluids are described and the physical effect of microgra-vity is divided into two kinds—the first grade effect and the second gradeeffect by the mentioned ideas.We have made a relationship between spaceprocessing of various materials and the second grade physical effect ofmicrogravity,and also made and estimation for the microgravity level,onwhich various physical effect of microgravity would occur,respectively.
