目的 提高空投大件在包装中重心调整的精准度，简化重心调整步骤。方法 先确定重心点的位置，再通过计算得出吊挂钢索的长度，再进行适当的配重和调节来调整重心。结果 与传统的重心调整方法相比，优化后的方法操作简单，调整准确，优化效果显著。结论 该方法可广泛适用于空投包装中大件重心调整操作作业。

The work aims to improve the adjustment accuracy of center of gravity for big-airdrop packaging and simplify the adjustment procedures. The position of the center of gravity was firstly determined and then the length of the hanging cable was calculated, and lastly proper counterweight and adjustment were conducted to adjust the center of gravity. Compared with the traditional adjustment method, the optimized method was simpler and more accurate and effective. In conclusion, the method can be widely used in adjusting the center of gravity for big-airdrop packaging.
