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。
