| 摘 要： | 利用激光光速控制、捕获生物体问题的数学模型，针对捕控对象所处的位置偏离光轴的情况，详细计算和讨论其受力特性，对于不同实验条件和不同的捕控对象，只须将具体的参数作相应的变换，即可直接应用此分析方法，分析结果表明，捕控对象的线度和离轴距离是影响归轴力的主要因素。

| Abstract: | A mathematical model is advanced for further analysing problem of living organism controlling and trapping by laser beam. Aiming at the condition that the trapped object was in a position deviated from optic axis, its force charactercstics is computated in detail and discussed. This analytical method can be directly applied to different trapped objects under different experimental condition only by corresponding transformation of specific parameters. As indicated by results of analysis, the dimension of trapped object and its distance away from axis are the principal factors influencing axial inclination force. |
