1·Aim: To measure mass, centroid and centroidal deviation of projectile body.
目的：对弹体的质量、质心及质偏进行测量。
2·This article tries to show, with the help of the formula of rotated axes, that centroidal axes of equilateral polygon is the centroidal axes and gives the research on its application.
本文利用转轴公式，对正多边形截面的任一形心轴均为其形心主惯性轴的结论进行证明，并对其在理论分析中的应用进行探讨。
3·Based on the principle of compound pendulum, the measurement method and corresponding equipment for the centroidal deviation and the rotary inertia of rocket projectile were described.
基于复摆原理，阐述了箭弹的质偏和转动惯量的测量方法及装置，推导出了质偏和转动惯量的计算公式。
