摘　　要：通过空气中声传播的规律及声线弯曲对反直升机引信动作区域性的影响，研究结果表明，确定声引信在空中的动作区域半径时须考虑温度和风的垂直分布的影响。In this paper,the sound proragation and ray tracing diagram in air midium are discussed,and the effects of variations of midium temperature and wind velocity with the height of propagaton of sound are explored.The research results have shown that these variations must be considered in estimating the receptance field radius of an acoustic fuze to insure giving the rein to the power of a mine weapon system.

关 键 词：声引信 声传播 动作区域性
