武汉理工大学硕士学位论文? ?论文最后分析了高温环境下液化气容器爆炸的事故机理，即高温环境下液化气容器爆炸的主要诱因为： 1 ）阀门打开时的压力骤降； 2 ）容器壁温度过高，导致容器壁的材料强度降低； 3 ）容器壁的温度不均匀引起的热应力。 |
| 10. | On the basis of displacement - time series of the slope , a nonlinear dynamic model is set up according to backus generalized linear inversion theory in this paper . due to the equivalence beween autonomous gradient system and catastrophe model , a standard cusp catastrophe model can be obtained through variable substitution . the method is used in analysis of displacement data of huangci landslide and wolongsi landslide and in understanding how slopes evolve before sliding . the result shows that the nonlinear dynamic model can make satisfactory prediction result . is it most important that there is a sudden fall of d , which indicates the occurrence of catastrophe ( when d = 0 )
研究表明，滑坡变形失稳过程具有混沌和分维特性，可以用分形理论来研究滑坡预测问题，基于对任一连续函数，至少在较小的邻域内可以用多项式任意逼近的数学理论，运用改进的backus广义线性反演理论，以斜坡位移时间序列为基础，反演了斜坡演化的非线性动力学模型。并利用自治梯度系统与突变模型的等价性，通过变量代换得到标准的尖点突变模型。 |
