周期强迫Fokker-Planck方程的时变解是确定的，遵循迭代过程。验证了该体系的混合性能。在不同的噪声强度区域，对自相关和信噪比的增强进行了区分和定位。阐明了绝热近似成立的条件和系统改进绝热结果的途径。
The time-dependent solution of the periodically forced Fokker-Planck equation is determined, following an iteration procedure. The mixing property of the system is verified. The enhancements of the autocorrelation and the signal-to-noise ratio are distinguished and localized, in different noise strength regions. The conditions for the validity of the adiabatic approximation and the way to systematically improve the adiabatic result are clarified.
