上旋壳

In general, the deformation pattern of ellipse shaped shell in dieless spinning is similar to that of a rotary one. Therefore, it is possible to spin a deep elliptic cylindrical shell if a cylindroid mandrel is adopted.

从总体上看，椭圆形锥壳零件的无芯模旋压和回转形锥壳无芯模旋压的变形规律相类似，由此可以推测，利用椭圆柱形芯模实现椭圆形深筒零件的旋压也是可能的。

The material for formation of the granitoids isderived from mixing sources of crust and mantle, with decreasing in crust-derived componentsfrom early to late.5. The tectonic setting for formation of the Mesozoic granitoids in the region isdefined as a post-collisional setting. The occurrence of a small part of rocks with characteristics ofcollisional or anorogenic granitoids provides evidence for the continuous process oftransformation of tectonic regime from collisional through post-collisional to anorogenic.6. Themultiple cycles of mantle-derived magma underplating caused by the multiple stages oflithospheric thinning in the Mesozoic result in the partial melting of middle to lower crust orcrust-mantle syntexis to form magmas. The crystallization of these magmas emplacing afterfractionation is responsible for the formation of the Mesozoic granitoids in this region.

形成花岗岩类的成岩物质来自壳幔混源。5、河南省西部地区中生代花岗岩类成岩构造环境为碰撞后环境，部分岩石具有碰撞期或非造山期花岗岩的某些特征，表明碰撞后阶段既是碰撞造山过程的延续，又是向非造山环境的构造转换时期，因而其岩浆活动在一定程度上仍然继承了碰撞前消减时期和碰撞时期已经活化的岩浆源区性质。6、研究表明，区内中生代多阶段的岩石圈减薄作用引发多旋回的幔源岩浆底侵以及中下地壳的部分熔融或壳幔同熔，由此形成的岩浆经分异演化后侵位可以形成区内的中生代花岗岩类。

It shows extremely close similarities to the Upper Jijicao Group in Junggar Basin in fossil assemblages such as pollen, bivalves and fossil plants, as well as sedimentary characteristics, it is adopted the same stratigraphic nomenclatures, namely Wulabo, Jingjingzigou, Lucaogou and Hongyanchi Formations in ascending order.

根据孢粉、双壳类、植物等化石组合以及沉积旋回和岩性等特征表现出来与准噶尔上芨芨槽群的一致性，采用了统一的地层名称，即乌拉泊组、井井子沟组、芦草沟组和红雁池组。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
