This paper first elaborated the principle of SINS, some interrelated information,and the affect of renewed arithmetic to the system"s precision. Then, we studied thequaternion in traditional renewed attitude arithmetic. The quaternion is simple, andwhen run it into computer, it"s time saving. So, this arithmetic is often adopted byengineering. However, the quaternion brought unexchangeable error inevitably. Whenthe carrying body moves in highly dynamic situation, the error would become larger.So we should take effective measure to get over it.

本文首先论述了捷联式惯性导航系统的工作原理及相关知识，捷联惯导系统姿态更新算法对系统精度的影响；其次研究了传统的姿态更新算法中四元数法，该算法简单，计算量小，因而在工程中经常被采用，但是在四元数法中不可避免的引入了不可交换性误差，特别是在载体处于高动态环境时，这种误差就会很大，必须采取有效措施加以克服。

In the second chapter, the mechanics principle of USF is introduced. How the defects cause measure error is calculated, and draw a conclusion: the unideal velocity profile causes large error when the meter calcs flow rate by a ideal meter constant.

论文的第一章以大量的国内外文献为基础，全面论述了流量计的发展历史和现状，确定以最有发展前途的流量计之一――气体超声波流量计为研究内容。
