航天器微流星体及空间碎片防护结构性能分析
Most of the spacecrafts are suffering from the bad space environment, and the space debris, included meteoroid and orbital debris, imperiled the spacecrafts most.
其中对航天器威胁最大的就是空间碎片,包括微流星体和轨道碎片。
Star volume is a contemporary stereological parameter reflecting the (mean) local size of an arbitrary structure (especially an irregular structure), and can be unbiasedly estimated by measuring the point-sampled intercepts.
星体积是反映任意结构(尤其是不规则结构)的(平均)局部大小的体视学新参数,可据点取截距测量进行无偏估计。
