以苏打饼干单片和单包为研究对象，应用破损边界理论，设计相关实验，测试饼干在不同破损率条件下各个方位的速度变化及加速度，构造出饼干的破损边界曲线。
Tests was carried out on cookies both in single and package unit to measure its velocity change and acceleration in different orientation in different damage rate based on damage boundary theory.
本文将方位角变化率测量信息也引入该定位问题，提出了基于MGEKF（修正增益扩展卡尔曼滤波），对三维运动辐射源的无源定位跟踪算法。
In this paper, the azimuth angle changing rate measurement is introduced into this passive location problem and a location algorithm for 3-D moving emitters based on MGEKF is given.
