This dissertation's main work and innovations is following: 1. The 6DOF kinematic and dynamic equations of motion for multiple thrusters AUV are derived and presented in a compact form using vector notation. The hydrokinetics of the MTAUV is classified anew. The MTAUV has two kinds of work modes which are cruising and hovering. The fluid dynamical mathematics description of the MTAUV is given anew. 2. The kinetics equations of the MTAUV in the low speed hovering are analyzed and studied.

本文主要的工作和创新点主要有以下几个方面：一、采用矢量参数的形式建立了基于多推进器自主水下航行器的六自由度运动学方程和动力学方程；对基于多推进器自主水下航行器的流体动力进行了重新分类，给出了基于多推进器自主水下航行器在巡航工作模式和悬停工作模式两种不同工作状态下流体动力的数学描述。

It is a new form of energy dissipation which is based on the theory and method of the multi-submerged jets in hydromechanics and it is the development of the hydraulic jump dissipation .

多股多层水平淹没射流消能既是传统水跃消能形式向复杂空间三元水跃消能形式的发展，也沿袭了流体力学中关于多股淹没射流研究的一些思想和方法，可以说是一种新型的泄洪消能方式。

In order to draw a circle around coarse sand concentrated coming area in sediment-laden and coarse sand area of the middle Yellow River,the paper makes macro analysis on the factors of geological structure,lithology of stratum,category of landforms and hydrometeorology of the sediment-laden and coarse sand area in the middle Yellow River and regional difference related with coarse sand production.

为在黄河中游多沙粗沙区确定粗泥沙集中来源区，从黄河中游多沙粗沙区地质构造、地层岩性、地貌类型、水文气象等因素与产粗泥沙关系的区域差异对粗泥沙集中来源区进行了宏观判析，认为在黄河中游多沙粗沙区范围内，吴旗—志丹—延安—延长一线以北、东胜—准格尔—清水河一线以南、吴旗—榆林—神木—大柳塔一线以东至晋西北黄河沿岸的范围是侵蚀最为严重的地区，也是粗泥沙集中来源区的宏观待选范围。

The analysis shows that the residual of the multi-spectral image with high resolution can be recovered by substituting the simplex portion obtained by decomposing the low-resolution multi-spectral image with hypercomplex residual image of a high-resolution panchromatic image, and the fusion of the multi-spectral image and the panchromatic image can be achieved by synthesizing symplectic decomposition.

分析表明用高分辨率全色图像的超复数残差图像来替换低分辨率多光谱图像分解后得到的simplex部分，就可以恢复出高分辨率的多光谱图像的残差，最后通过symplectic分解的合成实现多光谱图像和全色图像的融合。

Hyperkinesia, division and depression, bluedevils and aggresive were common among boys; against discipline, division and constraint and other problems were common among girls.

三地男生以多动、分裂强迫、抑郁、残忍等问题出现较多；女生以其它问题、违纪、分裂强迫、躯体诉述等多见。

For instance, highly multithreaded tasks or situations where many small tasks that are more I/O than CPU bound - like networking or database search - proceed in parallel.

例如，高度多线程任务的情况下，或许多小任务的多个I / O比约束的CPU -如网络或数据库搜索-平行进行。

Therefore, no matter the ideal companion the general meeting has not the perfect place in the reality, more importantly we see opposite party merit, but contains opposite party shortcoming, the multi-exchanges, the multi-communications, believed that each other can approach gradually toward the ours boundary of ideal.

所以，不管理想伴侣在现实中总会有不完美的地方，重要的是我们多看到对方的优点，而去包容对方的缺点，多交流、多沟通，相信彼此都会渐渐地朝着我们的理想之境靠近。

Make promotion more, can exchange a link more, increase external link, it is to mix others exchange link, 2 it is to go of Baidu stick, know and other places just sends a card, 3 it is stationmaster of much associate with, can take a few your websites sometimes, 4 it is to arrive above A5 hair post, there is link above idiograph (the card that here does not encourage everybody to send a few rubbish in A5, can help others) as far as possible.

多做推广，可以多交换链接，增加外部的链接，一是和别人交换链接、二是去百度的贴吧、知道等地方发帖子，三是多结交站长，有时可以带一些你的网站，四是到A5上面发帖，个人签名上面有连接(这里不鼓励大家在A5发一些垃圾的帖子，尽量能够帮到别人)。

Students should employ learning methods such as to read, to consult the dictionaries and to think as much as possible, in order to understand the charm of English and what idiomatical English is like, and then to use it in their own writing.

学生应采用多读、多查、多悟的学习方法，以体会英语的语言魅力并在此过程中体会到地道的英语，以应用到写作中去。

The result of study find out that the operator of Kenting area are choosing low-cost marketing method, most of operator are running marketing inactively, using of network marketing is less.

本研究结果发现垦丁地区之民宿业者基於其民宿行销特性，多选择较低花费之行销方式，且积极经营行销者为少数，网路行销工具之使用更不多见，然善於使用网路行销业者其经营状况大多良好，使用效益多属正面回馈，其成本低、传播速度快、多媒体丰富性高、互动性强，利用网路相关平台做为行销工具很切合业者简单又不高成本的要求。
