The carbonate source rocks of middle - upper ordovician in tarim basin are widely distributed in different sedimentary environments at the same period such as platform margin slope , platform inner sag , continental shelf , abyssal basin , etc 摘要塔里水盆地中上奥陶统碳酸盐岩烃源岩在同一时期不同的沉积环境（台缘斜坡、台地内凹陷、陆棚、深海盆地等）中均有发育。
Observational physical oceanography includes topics such as the physical description of the sea , the physical properties of seawater , methods and measurements , wind - driven ocean circulation , abyssal ocean circulation , boundary processes , and wave motions 观测物理海洋学所含括的主题如下?海的物理描述、海水的物理特性、方法与测量、风成海洋环流、深海海洋环流、边界过程、和波动等。
Nowadays the development of abyssal aquaculture cages is playing an increasingly important role in the sea farming industry in china but meanwhile , there are still some problems arising the sea farming industry in china focus on shoals and bays with good protection in which the water depth is small while the aquaculture density is large . these factors in addition to the pollution problems in the coastal gone have descended the quality of fishes , thus have had some negative effects on the economic benefits 目前我国海水网箱养殖业发展迅速，日渐成为渔业发展中的一个重要产业，在发展的同时，也暴露出一些问题：我国海水养殖主要在浅滩、掩护较好的海湾内，水深较浅，养殖密度大，加上近岸水域的污染，使鱼品质下降，经济效益受到一定影响。
The main achievements of the thesis include : 1 the model design of abyssal aquaculture cages ; 2 the hydrodynamic characters of the cages under the action of pure current in the states of floating vs submerging ; 3 the hydrodynamic characters of the cages under the action of pure wave in the states of floating vs submerging ; 4 the hydrodynamic characters of the cages under the joint action of currents and waves in the states of floating vs submerging ; 5 the effects of currents and waves on the exciting forces and motion of the gravity cages 漂浮状态和下潜状态相比，在单纯流作用下，网箱的水动力特性； 3漂浮状态和下潜状态相比，在单纯波浪作用下，网箱的水动力特性； 4漂浮状态和下潜状态相比，在波浪水流共同作用下，网箱的水动力特性； 5
According to the differences of sedimentary facies and environment , the source rock are divided into four types such as lime - mud reef in platform margin , platform inner sag , deep - water flat slope or continental shelf , abyssal basin , the lime - mud reef type is distributed in platform margin of upper ordovician , the remained three types are widely distributed in cambrian - ordovician system 根据沉积相带与沉积环境的不同，可将烃源岩划分为在不同沉积环境中的4种类型烃源岩；台地边缘灰泥丘型烃源岩、台地内凹陷型烃源岩、深水缓坡与陆棚型烃源岩、深海盆地型烃源岩。
Internal waves are a kind of bridge relating the diapycnal mechanical mixing to external sources of mechanical energy : first , internal waves are driven by wind stress and barotropic tide so that large amount of mechanical energy are transported to abyssal ocean with propagation of internal waves ; second , the mechanical energy can directly be cascaded to mixing through instability and breaking of internal waves 内波是外界提供的机械能与混合之间联系的桥梁之一，一方面风和潮汐通过激发内波，将能量向深海和大洋内区传递，另一方面，内波的不稳定和破碎直接将机械能串级到小尺度湍流混合中去。开展倾斜地形上内波的传播以及内潮的产生等方面的研究对海洋混合过程的参数化以及混合对大洋环流的影响等方面的研究具有重要的科学意义。
