摘　　要：研究了欧拉角定义的物理奇异性和欧拉方程求解的计算奇异性,分析了运载器垂直出水弹道姿态角定义面临的问题,提出用反欧拉法来定义和考核运载器出水弹道的姿态角。最后分析了应用反欧拉法姿态角定义的可行性及其对内测系统的要求。For the physical singularity of Euler angle, the heading and rolling angle are undefined when the carrier is launched horizontally and exits from the surface vertically, which cause a series of problems to interior-testing systemcalculation and water-exit parameters checking. In this paper, the physical singularity and computational singularity of Euler angles are investigated, then the problems encountered in defining the water-exit pose angles of the carrier areanalyzed, and anti Euler method is introduced to solve these problems. Finally,the feasibility of applying anti Euler method and the request on interior-testing system are analyzed.
