| 中文摘要: |
| 本文在运用李亚普诺夫(Ляпунов)第二方法讨论水电站调压室水位波动稳定性问题的过程中，通过对所构造的李亚普诺夫函数V(x)所代表的物理意义进行分析，认为李亚普诺夫稳定性判别条件过于苛刻。本文提出了拓宽后 的稳定性判别条件，并应用于水电站调压室水位波动稳定性问题的研究。其结果与数值计算结果吻合较好。 |
| 英文摘要: |
| Throught the analysis of the physical meaning represented by Ляпунов function being constructed, this paper considers that Ляпунов′s stability judgement terms are too harsh on the discussion of water level oscillating stability in the surge tank of water power station. The developed stability judgement terms are provided and applied in the study on the water level oscillating stability. The results of the study is in good agreement with the numerical calculation. |
