| 摘 要： | 导出了近地卫星上任意部位微重力水平的表达式,分析和近似估算了利用我国返回式卫星进行首次空间材料加工试验时的微重力水平,表明是在按轨道周期变化的优于1×10~(-5)g_0的准稳态加速度上,迭加了幅度不超过2×10~(-4)g_0的随机加速度脉冲干扰。我国在1987年8月5日发射的返回式卫星上,首次搭载了一台空间晶体生长炉,在空间微重力条件下进行了以砷化镓为主的十项材料加工试验。为了对所得结果进行科学的分析,就必须知道晶体生长期间的微重力水平。本文结合卫星的实际运行参数给予了估算。

| Abstract: | In this paper, the expression of the microgravity at arbitrary point in a near-earth satellite was presented.The levels of microgravity of the first test of space material processing in the chinese recoverable satellite were analysed and approximately estimated.It is showed that the level of microgravity is less than 1×10~(-5)g_0 which varies quasisteadily with the period of orbit and is added by the random acceleration with amplitude less than 2×10~(-4)g_0. |
