trench mortar

The war broke out in north Kosovo of Yugoslavia , the noise of musketry and trench mortar is continuing around .

南斯拉夫科索沃省北部爆发战斗，步枪和迫击炮声不绝于耳。

Aiming to some projectiles of trench mortar , the probability error of the experiment without controlling flight is about 1 % . Monte Carlo target practice was used in the same calculating condition .

针对某型迫弹无控飞行时的试验中间概率误差约为1%，利用蒙特卡洛打靶法，在相同的计算条件下，若末段采用脉冲控制，仿真计算得到其圆概率误差小于等于4m；

This paper thoroughly analyzes kill efficiency of trench mortar ammunition which adopts prefabricated fragment and proximity fuse , by establishing kill efficiency estimated model and using experiment data , we draw some beneficial conclusion at last .

文章通过建立迫弹杀伤能力计算模型，结合靶场试验数据，对迫弹采用预制破片和近炸引信后的杀伤能力进行了深入的分析，得到了许多有益的结论。
