本文研究了谐振子频率跳跃压缩机制的理论基础。结果发现，相关的压缩变换存在，但其解释的频率变化是不可能的。的重新解释的结果在坐标或动量变量的标度变换。此外，突然的跳跃并不是必需的，挤压可以不断演变。得到了这一过程的运动方程，并得到了导致压缩的相互作用。
The theoretical basis of a mechanism for squeezing through a frequency jump of a harmonic oscillator is examined. It is found that a related squeezing transformation exists, but its interpretation in terms of a frequency change is not possible. A reinterpretation of the results in terms of a scaling transformation in coordinate or momentum variables is given. Moreover, a sudden jump is not essential, and squeezing can evolve continuously. The equations of motion for such a process are obtained and the interaction responsible for squeezing is obtained.
