摘要

摘要首次研究了声音对定向多极源在波导中形成的矢量-标量场的相位不变量特性。研究表明，即使使用这种复杂声源，相位不变量对声压和振动速度矢量的投影也是有效的。它实际上并不取决于声源的指向性和频率、接收器与声源之间的距离或波导的参数。

Influence of the Direction of Sources on the Phase Invariants of Vector–Scalar Fields in a Shallow Sea

For the first time, the properties of the phase invariant of sound to vector–scalar fields formed in a waveguide by directional multipole sources are studied. It is shown that, when even such complex sources are used, the phase invariant is valid for sound pressure and for projections of the vibrational velocity vector. It practically does not depend on the directivity and frequency of the source, the distance between the receiver and the source, or on the parameters of the waveguide.

期刊介绍： Doklady Physics is a journal that publishes new research in physics of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
