| 摘 要： | 按照相对地球的惯性坐标系，根据动能定理，首先推导得出了回收物为“有限质量”情况下的拉直力计算公式，而后又根据回收物为“无限质量”的假设，得出了与文（１），（２）相同的拉直力计算公式。在推导中，文（３）方程中一项∫＾ＬｍａｘＬｓＰｄＬ修正为∫＾ｘｍａｘⅡ０Ｐｄｘ。

| Abstract: | Based on the earthbound inertial coordinate system and the kinetic energy theorem and under the finite mass of recovery body condition, equations for calculating the snatch force are developed,and then on the assumption of infinite mass of recovery body,the same equations for calculating the snatch force as that of Refs 1] and 2] are obtained. The PdL in equation of Ref. 3] is corrected to be Pdx. |
