水雷引信的声遥控（安全、危险、自毁）显著提高兵器威慑作用的灵活性和电子对抗能力。但是海中声传播信道十分复杂多变，可导致可靠的声遥控作用距离严重下降。文中讨论影响水声传播途径最重要的因素──海中声传播速度的垂直分布、声传播路径及声源深度配置的关系，目的是使被控水雷的声引信正确处于声束照射区，以获得最大可靠作用距离。
Remote control (safety, danger, self-destruction) of the mine fuze significantly enhances the flexibility and electronic countermeasure of the deterrent effect of the weaponry. However, the sound propagation channel in the sea is very complicated and changeable, which can lead to serious decline of the reliable sound remote control effect. In this paper, the most important factors influencing the path of waterborne transmission are discussed - the vertical distribution of sound velocity in the sea, the relationship between the path of sound propagation and the depth of the sound source. The purpose is to make the acoustic fuze of the controlled mine lie in the sound beam irradiation area The maximum reliable distance.
