强迫Duffing方程的研究报告，特别提到的区域的参数空间，五个不同的吸引子共存。这种共存，在最近的一些实验中报道，被称为广义多稳态。外部噪声的作用，否则不相交的盆地桥接进行了探讨。噪声引起的耦合被证明是由简单的动力学方程下的边界的几何形状的一般假设。这些动力学方程产生的低频功率谱与实验结果定性一致。
A study of the forced Duffing equation is reported, with particular reference to a region of the parameter space where five different attractors coexist. This coexistence, reported in some recent experiments, is called generalized multistability. The role of external noise in bridging the otherwise disjoint basins is explored. Noise-induced couplings are shown to be ruled by simple kinetic equations under a general assumption for the geometry of the boundaries. These kinetic equations yield low-frequency power spectra in qualitative agreement with the experimental results.
