摘要
采用数值模拟给出水平均匀波导环境下的声场强度在R-ω平面上的“纹理”图案,根据相位及任2号简正波之间的水平相干距离[1]随频率的变化,分析了平面中存在的“分裂”和“孤立的干涉线”2种干涉“纹理”的形成机理。
Sound intensity interference striations in the range-frequency plane （R-omega plane） in a horizontally homogeneous waveguide are studied by using numerical simulation. There exist evident interference patterns such as “splited-line” and “isolated-line” in the R-omega plane. Based on the variation of the phase and horizontal interference wave-length of the interference terms with the change of the frequency, the mechanism of these interference striations is investigated in detail.
