自谐振孤子和衰变泵浦

Autoresonant soliton and decay pumping

O. M. Kiselev

摘要:

推导了在外力作用下频率缓变的偏导数主共振方程。当时间较长时,渐近解的首阶项被构造为振幅增长的孤子。由于外力幅值的衰减而得到该增长解。得到了耗散介质中解增长的一个必要条件。

英文摘要:

The primary resonance equation in partial derivatives with external force and slowly varying frequency is derived. The leading-order term of asymptotic solution is constructed as a soliton with growing amplitude when time is large. This growing solution is obtained due to the decaying amplitude of the external force. A necessary condition for the growth of the solution in dissipative media is obtained also.
