The difference between the crust shortening rates in west and east direction of Tianshan, is resulted from the pushing action by Pamir and the clockwise rotation of Tarim. In the west Tianshan (west to 75°E), the convergence is caused by the push of Pamir in NNW direction, and in the east to 75°E, the difference of tectonic deformation is caused by the clockwise rotation of Tarim.

从天山南北山前断层缩短速率的东西差异分析，造成天山东西变形差异显著的原因是帕米尔北向推挤和塔里木顺时针旋转的共同作用：在天山西端(75°E以西)，其挤压缩短(17mm/a)是由于帕米尔高原北北西向的推挤作用；而75°E以东的地区，其差异构造变形的原因则主要是塔里木顺时针旋转的结果。

Motivated by Baker\'s result, we introduce a functional index‖E‖_∞to prove that if a mapping f which is from a normed space to a normed algebra satisfying‖ab‖=‖a‖‖b‖satisfies that‖E‖_∞is bounded,then either f is bounded or f is exponential.

受到Baker的结论启发，通过引入一个泛函指标‖E‖∞，证明了从赋范空间到满足范数可乘性的赋范代数的映射f，只要满足‖E‖∞是有界的，则f要么是有界的，要么是指数的。

The finest music - in the two sonatas with obbligato harpsichord in B minor and A major, and in two with continuo alone, in E minor and E major - is top-drawer Bach , probably composed in the 1730s, teeming with melodic invention designed to put the newly fashionable instrument through its paces.
