查询词典 isostasy

The earlier rift Phase is composed of two sub-rift episodes withquick subsidence, and the later thermal subsidence was superimposed with rapidsubsidence related to crustal isostasy induced by higher density mantle and cooling ofthe lithosphere.

渤海盆地内的后期热沉降叠加了12Ma以来由高密度地幔及岩石圈冷却诱发的快速均衡沉降。

In central Himalaya, massif was mainly uplifted in the tectonic model of channel flow during 17~7 Ma at a velocity of ~2 mm/a, then was extruded to earth surface at a much lower velocity. In eastern Himalaya Syntaxis, massif was mainly uplifted in the structural style of titling at a background of isostasy since 4.0~2.2 Ma.

喜马拉雅中段主要在17~7 Ma前以通道流的方式快速隆升，之后的抬升过程相对缓慢；东喜马拉雅构造结则主要在3 Ma以来，以地壳均衡作用为背景的掀斜式抬升为主要隆升模式。

The essential reason for this problem comes from the thermally-caused lithospheric mantle density variation effects on the isostacy models: in traditional isostasy models, the effects from mantle lithosphere are excluded.

观测表明，大陆地区存在很多传统均衡模型无法解释的现象，其根本原因在于传统均衡理论中没有考虑地幔岩石圈部分由于热结构差异导致密度差异的影响。

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。

Airy Hypothesis: A mode of compensation for isostasy in which topographically elevated areas are compensated by underlying "roots" of crustal material penetrating into the higher density subcrust.

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
