This method is based on the Snell law of the acoustic propagation in water. It utilizes the different velocity gradient among the linear layers, it is realized that drawing the sound ray picture and building the mathematical model about the geometric operation range. It predicts the geometric homing range through sound ray density. The result proves that this design has a good effect on the trial., authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null, correspAuthorsNote=null,

深弹贮存寿命试验是考核产品寿命能否达到可靠性设计指标的关键内容,试验方法的设计和实施直接影响试验的可靠性水平。针对影响深弹贮存寿命的主要因素和灵敏参量,依据深弹长期贮存寿命与温度等因素的关系,基于阿伦尼斯加速方程,设计了加速寿命试验方法来估计深弹贮存寿命。

To predict the acoustic homing torpedo’s geometric range under different hydrological condition, it is presented that a method which using sound ray’s density to determine geometric operation range. This method is based on the Snell law of the acoustic propagation in water. It utilizes the different velocity gradient among the linear layers, it is realized that drawing the sound ray picture and building the mathematical model about the geometric operation range. It predicts the geometric homing range through sound ray density. The result proves that this design has a good effect on the trial.
