内容摘要：本文以上海综指和深圳综指为研究对象，研究1990年12月至2005年8月的上证综指和1991年12月至2005年8月的深圳综指的静态有效性和动态有效性，及可能的渐进有效路径。

By means of forced synchronization of current in thyristor branch with the line current, the mode switching from capacitive mode to Bypass can be implemented. In the switching strategy from capacitive mode to inductive veriner mode, a method of thyristor conditional firing is put forward. The thyristors will be fired and conducted on condition that both line current and capacitor voltage are inphase.

Through the experiments of three kinds of models mentioned above, the structural deformations of "outflow-extension","strike-slip-extension" and "uplifting-extension" are studied and some viewpoints involving that the plastic flow in the lower lithosphere controls the extensional structures are stated as follows:(1) Regional extensional structure does not result from the direct extension along the upper crust, but from the plastic flow in the lower lithosphere and its dragging and stretching the upper crust;(2) Deformation of continental extensional structure resulted from the active uplifting of mantle is conditional that the significant extension occurs only in the models with free- or outflow-boundary condition on both sides, whereas the passive uplining of mantle exists widely, because it is an inevitable consequence of the efiect of thermo-gravity isostasy;(3) Strike-slip shearing in the lower ductile lithosphere, including site-restricted and site-unrestricted shearing, can result in various types of extension structures;(4) The"graben-horst"type extensional structures can be formed in difierent mechanisms, including outnow-extension, shear-extension, uplifting-extension and their synthetical action.

通过上述三种模型的模拟试验，比较系统地研究了"泄流-伸展"、"走滑-伸展"和"上隆-伸展"等构造变形，提出岩石圈下层塑性流动控制了各种伸展构造变形的观点，主要包括以下几方面：(1)区域性伸展构造不是上层直接受到拉伸，主要是下层流动牵引上层伸展；(2)地幔主动上隆引起大陆伸展构造变形是有条件的，需要侧边伸展或不受约束的边界条件，而被动上隆广泛存在于地壳断裂或减薄部位，是热和重力均衡的必然结果；(3)下层塑性流动中的走滑剪切，包括限位剪切或非限位剪切，可以引起不同型式的伸展构造；(4)总结了"堑-垒"型伸展构造的多种成因机制，包括泄流、走滑、上隆及综合作用均可形成"堑-垒"构造，但组合形式不尽相同。

Based on 1-D Markov chain model, conditional 1-D Markov chain model is discussed in the fourth part.

在一维Markov链模型的基础上，讨论了条件化的一维Markov链模型。

Basing on this, this article deeply analyzes the relations between implication and the connective "If, then" used in ordinary logical thinking, and points out that material implication is scientific abstract generation to the ordinary language "If, then". Their sameness lies in: when a conditional's protasis is true and its consequent is false, material implication equation is false.

在此基础上，论文深入地分析了蕴涵与人们极易混淆的日常逻辑思维中的"如果，则"的关系，指出实质蕴涵作为数理逻辑中对日常语言"如果，则"的科学抽象地概括，二者的相同点在于：当前件真后件假时，充分条件假言判断为假，实质蕴涵式也为假。
