将连续介质中的化学反应过程建模为具有δ相关随机力的一对随机方程。给出了一种准一维近似计算速率常数的数值方法。精确的速率常数可以在广泛的系统特征参数范围内找到。证实了Berezhkovskii和Zitserman先前预测的具有非平衡动力学行为的重要区域的存在。此外，非平衡速率常数不仅可以描述准一维动力学的极值，还可以描述完全二维运动方程的情况
A chemical reaction proceeding in a continuum medium is modeled as a pair of stochastic equations with a δ-correlated random force. A numerical method for calculating the rate constant is elaborated in a quasi-one-dimensional approximation. Exact rate constants are found over a wide range of characteristic system parameters. The existence of a significant region with a nonequilibrium kinetic behavior, as predicted previously by Berezhkovskii and Zitserman, is confirmed. Moreover, the nonequilibrium rate constant is shown to describe not only the extreme of quasi-one-dimensional dynamics but also the case when the complete two-dimensional equation of motion operates
