摘　　要：在HE射弹破片场呈圆锥形、破片分散在各个子锥面、破片数在飞散锥内随锥角服从均匀分布的前提下,假设同一锥面层上相邻两破片间的距离与其所在层到相邻外层锥面的层间距相等;根据“宏观可控、微观随机”的破片分布实际,引入相应的随机变量,推导了射弹静爆时单一破片的飞散角及方位角,给出了相应的轨迹方程和速度计算公式;推导了动态条件下破片相对大地和相对目标的速度计算公式和飞行轨迹参数方程;根据射弹破片质量服从Mott分布、破片质量在飞散空间均匀分布的假设,推导了单一破片的质量。Based on precondition of cone-shaped HE projectile fragment field, fragment centralized distribution in different cones and fragment homogeneous distribution in the same cone, further supposing that the space between adjacent fragments in the same cone is equal to the space between adjacent layers, according to the factual ‘macroscopically controllable and microcosmic random’ fragment distribution, the flying angle and azimuth angle of single fragment in static detonation are inferred by the way of random variables, the track equation and velocity formula are given, the expressions of the velocity relative to the earth and to the target and the flying track equation are deduced in dynamic state, in case of Mott distribution of fragment mass and homogeneous distribution in flying space, the mass of single fragment is inferred.
