摘　　要：介绍了飞行器设计相关学科中欧美坐标系和苏联坐标系之间的异同,分析了两种坐标系体系建立的依据、牛顿力学体系下的一致性以及对飞行器运动参数、稳定性判断的影响,给出了两种坐标体系之间的变换公式。最后,对教学和科研中采用何种坐标系提出了建议,以此帮助广大科研人员了解两种坐标系的来源,熟练掌握科研工作中各坐标间的关系和变换方式。This paper introduces the similarities and differences between the European-American coordinate system and the Soviet Union coordinate system in the aircraft design,analyze the basis of the establishment of the two coordinate systems,the consistency of the Newton mechanics system and the influence on the aerodynamic parameters and stability judgment of the aircraft,and the transformation formula between two coordinate systems is given.Finally,some suggestions are given for studying the coordinate system and scientific research.This paper could help the majority of researchers understand the source of the two coordinate systems,understand the relationship and transformation mode between the coordinates in scientific research.

关 键 词：欧美坐标系 苏联坐标系 统一性 稳定性
