牵引作用

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。

Exclusively produced from bush vines planted in 1908.rietvallei estate,one of the oldest wine producing estates in the robertson region,has been in the burger family since 1864.current owner and winemaker,johhy burger and fifth generation on the estate,is proud to prsent this special and traditional rievallei wine to you.muscadel was the first wine to be produred on the eatate.the wine is stillmade according to the original recipe as set out by the first winemaker on rietvallei, jacobus burger ,who also planted the bush vines,form which this wine was prouduced,in1908.this is a wine that we,as a family,cherish dearly,because it represents all thal is rietvallei...a fimeless family tradition.rietvallei 1908 muscadel is deep red in colour,full-bodied,rich,yet gentle.a floral bouquet comes throuth on the nose,with typical raisiny sweetness and an intense flaours that lingers on the palate and follows through on the afterteste.addintional bottle maturation gives excellent results.

好象这几篇翻译都是你发出的关于一个主题的。大概是有人向你推销葡萄酒或则是找代理销售商吧！Bush vine 成立于1908 ，作为独家生产商，它是一个最古老的葡萄酒基地在robertson 地区，早在1864年它就是burger家族企业，目前该所有经营者和制酒者 Johhy burger和第五代家族成员非常自豪的向你展现制造这种独特的传统配方美酒。muscadel是在这里制作的第一种葡萄酒，Jacobus burger，培育的葡萄园在1908就酿造了第一种葡萄酒，bugger家族人员非常珍爱这种葡萄酒，它就代表着rietvallei，一种家族传统的配方制作。muscadel 颜色深红，饱满柔和，香味牵引着鼻子。典型的葡萄干味道还有夹杂着深深的香味在嘴边不停的徘徊回味无穷。通过后来有关坚定，瓶装的发酵对此发挥了巨大的作用能力有限，供仁兄参考之用

Single factor experiments were done with the factors including the width of protrusion and the trolley's velocity, which showed that the surface frictional coefficient decreases with the width of protrusion increasing, and doesn't change with the trolley's velocity changing, which was consistent with the results of the orthogonal experiment. A theoretical model of the horizontal projection of a corrugated bionic surface's contact area was built, which showed that the contact area's horizontal projection decreases with width and interval increasing respectively and that the ratio of the contact area's horizontal projection and the vertical load decreases with the vertical load increasing. It indicated that the surface frictional coefficient decreases with the above three factors increasing respectively. Finite element modeling and analysis of interactions of a plate and soils was done using ANSYS, which showed that the plate frictional coefficient is little relative to soil elastic modulus and decreases with vertical surface pressure and that trolley's pull and vertical displacement of bionic surface's control pilot keep constant almost during the plate being pulled. Finite element modeling and analysis of interactions of a corrugated bionic surface and soils was done using ANSYS, which showed that surface frictional coefficient is little relative to soil elastic modulus and decreases with bionic surface's structural parameters and vertical pressure increasing. However, the three factors all didn't affect the surface frictional coefficient remarkably on the condition of 90% dependability. For the first time, bionic surfaces were applied to screw piles, which formed bionic screw piles, and the contrast experiments showed the bionic screw pile had certain resistance-decreasing effects.
