考虑两个耦合的长Josephson结，运用直接微扰法，讨论周期微扰下混沌孤振子的超辐射功率.结果表明：周期微扰下的孤子作混沌运动，当孤子逐渐与周期微扰同步时，辐射功率不断增大，其上限虽受解的有界性条件制约, 但通常比孤子对的辐射功率更大.理论分析和数值模拟均很好地说明了这一点.这为混沌孤振子的实际应用提供了理论依据.
We consider two weakly coupled Josephson junctions. Using usual perturbation technology we discuss the system hyperradiance from soliton perturbed by a periodic sinusoidal wave. The results reveal that soliton with periodic perturbation possesses chaotic behavior. When the soliton is nearly synchronized with periodic solution, the emitted power will rapidly increase. Although the boundedness condition limits its maximal value strictly, chaotic soliton oscillator emits much greater power than soliton pair in general. Theoretical analysis and numerical simulations both demonstrate the above results well. Those results gave theoretical basis for practical application.
