裂谷

Studies show that it is a set of turbidity sedimentary under the condition of deep-water environment in rift deep depressing period with the characteristics of multiphase and mutability, The lithology of reservoir is chiefly mid-fine grained conglomerate and lithic mixed sandstone, as well as the gravel-bearing sandstone next. Sand bodies in the plane are controlled by water channel obviously, resulting in NW-oriented banded distribution.

研究表明，大凌河油层是裂谷深陷期深水环境条件下形成的一套浊流沉积物，沉积物具有多期性和突变性，主要岩性以中－细砾岩和岩屑质混合砂岩为主，次为含砾砂岩，砂体在平面上受水道控制明显，呈北西向的条带状展布。

The tectonic evolution of southern Junggar basin can be classified into seven stages: stage of intracontinental rift from middle Periman to late Late Carboniferous; stage of weak extension and peneplane from late Permian to early Triassic; stable depression stage in middle-late Triassic; maximal basin formation phase in the setting of weak extension in early-middle Jurassic; inactive depressed basin formation phase in thrust setting in middle-late Jurassic; stable depression stage in Cretaceous and Eogene; foreland depressed basin formation phase in thrust setting in Neocene and Quaternary.

准噶尔盆地南缘晚石炭世以来盆地构造演化可划分为七个演化阶段：晚石炭世—中二叠世陆内裂谷作用阶段；晚二叠世到早三叠世处于弱伸展-稳定坳陷作用阶段；中、晚三叠世准平原化作用阶段；早、中侏罗世为弱伸展背景下广盆形成阶段；中、晚侏罗世冲断背景下的坳陷盆地形成阶段；白垩纪到古近纪弱伸展背景下的稳定坳陷盆地形成阶段；新近纪—第四纪为冲断背景下的前陆坳陷盆地形成阶段。

And the late Triassic bimodal association reflects the characteristics of intracontinental rift setting, the early Jurassic Raohe ultramafic - mafic rock - pillow lava association represent the environmental characteristics of oceanic island, magmatic arc association represent the characteristics of island arc and active continental margin with the background of the plate subduction, middle Jurassic syn-orogenic granodiorite-granite association reflects characteristics of matching and orogensis after continental accretion.

其中晚三叠世双峰式组合反映了板内裂谷成因特征，早侏罗世饶河超镁铁质-镁铁质岩-枕状熔岩组合代表了洋岛环境特征，岩浆弧火成岩组合代表了板块俯冲背景下岛弧和活动大陆边缘特征，中侏罗世同造山花岗闪长岩-二长花岗岩组合反映了陆缘增生后拼贴造山的成因特点，它们总体上代表了由被动陆缘裂向活动陆缘转化并最终发生陆缘增生带拼贴造山的一个演化过程，其间伴随有被动陆缘深海盆地沉积、活动陆缘弧后前陆盆地沉积和陆相类磨拉石建造

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
