相对于传统的均分空间封锁机场跑道方式，研究了切割封锁方式下跑道的毁伤效能问题.以概率积分的方法分析了仅存在开舱点位置偏差时，该文模型对应的3种不同的布撒形式下，布撒器对机场跑道的横向封锁概率、纵向封锁概率以及整条跑道的封锁概率，并进行了仿真计算.仿真结果表明，最优的布撒方案为下抛—侧抛—侧抛(侧抛—侧抛—下抛)形式.研究结果可为布撒器的总体设计提供依据.

Compared with the traditional averaging space modes, the damage probability efficiency of the cut blanked modes for whole airport runway was studied. The cross direction interdiction probability, longitudinal interdiction probability and the interdiction probability of whole airport runway were described with probability integral method under the conditions of three dispensing form mentioned, while open cabin position error existed only. The simulation was carried out. According to the simulated data, the optimization form of dispensing is adown throw lateral throw lateral throw(lateral throw lateral throw adown throw). The research provides reference for the general design of airborne dispenser.
