对于整体耦合振子的情况，给出了对表现为集体振荡的一组相互作用的非线性元件的宏观外部扰动的集体相位响应。宏观相敏度是由组成振荡器的微观相敏度通过两步位相还原得到的。应用这一结果，我们量化了两个非耦合振子群体在经历相干集体振荡时由共同噪声引起的宏观同步的稳定性。
The collective phase response to a macroscopic external perturbation of a population of interacting nonlinear elements exhibiting collective oscillations is formulated for the case of globally coupled oscillators. The macroscopic phase sensitivity is derived from the microscopic phase sensitivity of the constituent oscillators by a two-step phase reduction. We apply this result to quantify the stability of the macroscopic common-noise-induced synchronization of two uncoupled populations of oscillators undergoing coherent collective oscillations.
