近年来，Nicolis和Prigogine提出，在开放的化学体系中，围绕非平衡定态的涨落不能用通常基于“生灭”模型的随机描述来正确处理。根据这些作者的说法，通常的随机模型预测了波动的行为，该行为强烈依赖于反应的详细动力学性质，而对波动的更精确的相空间描述导致了关于稳态附近波动概率的广义爱因斯坦公式：
In recent years, Nicolis and Prigogine have argued1l that fluctuations around nonequilibrium steady states in open chemical systems cannot correctly be treated by means of the usual stochastic description based on the "birth and death" model. According to these authors, the usual stochastic model predicts a behavior for fluctuations which depends strongly on the detailed kinetic properties of the reactions, while a more precise phase-space description of fluctuation leads to the generalized Einstein formula for the probability of fluctuation around the steady state:
