摘　　要：环锭纺气圈的纱线形态是一空间曲线,其空间倾斜角将影响钢丝圈运动的力学平衡条件,而形成该空间曲线的主要原因是空气阻力。该空间曲线的精确计算比较繁复,本文以简单函数形式给出该空间曲线的正弦近似解,与精确解相对比其误差一般较小。The configuration of ring spinning balloon yarn is a spatial curve, and its angle of inclination will influence the force equilibrium of traveller motion. This spatial configuration is caused mainly by air drag, but the exact form of the curve is complicated to calculate. This paper, however, gives an approximate analytical form of the yarn spatial curve, which compares very well with that of exact solution calculated by numerical methods.

关 键 词：环锭纺纱 气圈空间曲线 空气阻力
