最后一个戏剧性标记室内到室外的转变在涨潮时透过防波提被强化出来；藉著每次海水的波送，激起的巨浪高升入天，浪花随之向下坠入成人池中，透过这样拥抱著自然野性和奔放的动态过程。

For example, if there are overexposure and/or underexposure, left and/or right peaks become large, and the remaining part of the histogram degenerates into thin strip on the bottom during normalization process.

放大倍数动态改变，以使至少20%的区域被使用，以方便观察直方图。裁剪的峰值会在顶端以红色标出。

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。
