Takahasi的波动耗散定理的推导重新审查，并推广到微正则系综。零频率磁化率与热力学绝热磁化率的相等性要求相关函数满足遍历条件，或者等价地要求相空间分布函数满足这样的条件，即当施加脉冲扰动时，相空间分布函数在长时间后达到适当的平衡分布。
Takahasi's derivation of the fluctuation-dissipation theorem is reexamined and is generalized to a microcanonical ensemble. Equality of the zero-frequency susceptibility to the thermodynamic adiabatic susceptibility requires an ergodic condition for the correlation function or equivalently the condition for the phase-space distribution function to attain a proper equilibrium distribution after a long time when a pulsive disturbance is applied.
