探讨性地定义了广义熵的概念；对于给定的模型方程，建立了相应的熵方程，揭示了模型方程潜在固有的耗散熵产非负定性质；提出了以该非负定性为准则，对模型方程的一般化数据格式稳定性限制条件的分析方法．针对一些典型的数值格式导出了具体的限制性条件，归纳性地显示该方法的结果为稳定性的充分条件，为耗散与数值稳定性的内在联系提供了新的理解 The conception of generalized entropy is tentatively defined. For a given model equation, a corresponding entropy equation is established, which reveals the inherent nonnegative qualitative entropy property of the model equation. Based on this nonnegative qualitative criterion, Analytical Method for Constraints of Stability of General Data Format of Model Equation. For some typical numerical formats, we derive the specific restrictive conditions, inductively show that the result of the method is a sufficient condition for stability, and provide a new understanding of the inherent relationship between dissipation and numerical stability
