Measurement error from the photoelectric theodolite is the main error in the ballistic trajectory measurement. 光电经纬仪测量元素误差是外弹道测量中最主要的误差源。
The phenomenon of aerodynamic heating and ablation for hypervelocity projectues seriously affects the characteristics of the exterior ballistics. 超高速弹箭存在的气动加热烧蚀现象会严重影响其外弹道特性。
