介绍、列出了中俄两国现行飞行力学标准；依据这些标准，对两国飞行力学方面的坐标轴系、术语、定义和符号进行了对比分析；指出两国的坐标轴系、术语、定义和符号体系基本相同，其间最大的差别是坐标轴的指向不同，从而造成一些参数的正负符号不同。 Introduced and listed the current flight mechanics standards of China and Russia; based on these standards, the coordinate system, terminology, definitions and symbols of the two countries in terms of flight mechanics were compared and analyzed; the coordinate axes, terms and definitions of the two countries were pointed out And the symbol system is basically the same, the biggest difference between the different directions of the axes, resulting in some parameters of positive and negative symbols are different.
