| 摘 要： | 在利用三角形前向展开法追踪温度梯度场中声线路径的基础上,尝试使用一种新的方法插值法,求取本征声线的出射角.通过使用插值法与传统的打靶法,对具体的温度场模型进行仿真计算,结果表明运用插值法计算本征声线出射角的精度和速度都要优于打靶法.

| Abstract: | On the basis of acoustic rays tracing in temperature gradient field with triangular forward development,a new method-interpolation method was trially employed to evaluate the emergent angle of eigen acoustic rays.Simulative computation was conducted for a typical model of temperature field with the methods of interpolation and shooting,respectively.The result showed that the both of computation accuracy and speed of the former were superior to the latter. |
