针对最小布雷间隔不适用于空投布雷作战的问题，提出了战术最小布雷间隔的概念。结合空投水雷弹道特性，分析了布雷散布误差影响因素，探讨了多枚水雷连续投放时散布误差的相关性问题,研究了战术最小布雷间隔的确定方法。最后仿真分析了考虑空投水雷散布误差时，战术最小布雷间隔的选取，以及对布雷作战效果的影响。

Since the minimum drop-interval is not applicable to air-launched mines,the concept of “tactical minimum drop-interval” is proposed.According to the trajectory characteristics of airdropped mine,the factors that have effect on dispersion error are analyzed,the dispersion error correlativity when multiple mines are dropped continually is discussed,and the mathematical models are established.Then,a method for determining the tactical minimum interval of airdropped mines is presented.Finally,simulation is made based on the mathematical models.The selection of the tactical minimum interval with consideration of dispersion error,and its effect on the operational effectiveness,are analyzed according to the simulation results.
