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。

Aiming at the question of undercut in high-speed welding,this paper presented the model of hydrostatics,mathematics calculation and experience of melten-pool.

针对高速焊接条件下的咬边问题，概述了熔池金属流体静力学模型、数值计算模型以及经验模型，并分析了各自的特点。

The atomic oxygen perpendicular distribution of the middle and upper atmosphere (100~500km) is simulated quickly and effectively based on the hydrostatics and mathematics software. The simulation results are compared with the data from MSISE-90 model, and they are coincident in order with certain difference in values.

基于修正后的流体静力理论和数学软件，对中高层大气100~500km 高度范围内氧原子的垂直分布进行了快速有效的模拟，将模拟结果与MSISE-90 模型提供的数据作了比较，二者数量级相等、仅数值有一定偏差。
