从波动非线性流体力学（扩展到短波长）出发，考虑详细的平衡约束，建立了过冷流体的自洽模式耦合模型。仅基于压力非线性的模式耦合模型预测的尖锐的玻璃化转变不会发生在这里。相反，密度自相关函数的长时间渐近行为由详细平衡约束所施加的附加非线性决定
A self-consistent mode coupling model for supercooled fluids is derived from fluctuating nonlinear hydrodynamics (extended to short wavelengths) with attention to detailed balance constraints. The sharp glass transition predicted by mode coupling models based only on pressure nonlinearities does not occur here. Instead, the long time asymptotic behavior of the density autocorrelation function is determined by additional nonlinearities imposed by the detailed balance constraints
