突变理论 [tū biàn lǐ lùn]
catastrophe theory
- 数学里有一个晦涩的分支叫“突变理论”，它研究一个小小的干扰是如何使一个先前稳定的系统突然之间发生戏剧性变化的。
There's an obscure branch of mathematics known as "catastrophe theory," which looks at how a small perturbation in a previously stable system can suddenly produce dramatic change. - 本文基于结构突变理论，研究了数据生成过程中的几种不同结构突变模式，并对结构突变的单位根过程和结构突变的趋势稳定过程给出了不同结构突变模式的检验方法。
Based on the theory of structural breaks, we studied on the different structural breaks models in DGP, and proposed its test methods, which can distinguish unit root with structural breaks from trend stabilization with structural breaks. - 为此，分析了岩盐溶腔顶板动态平衡过程及失稳发展机制，并利用突变理论研究了岩盐溶腔顶板失稳机理，探讨了溶腔顶板稳定性的影响因素，从而为溶腔稳定性拉制打下一定的理论基础。
Dynamic balance process and instability process of rock-salt cavity roof are studied, and instability mechanism of rock-salt cavity roof is studied with catastrophe theory, and the influencing factor are analyzed, which will be theoretical basis of rock-salt cavity stability control.
