摘　　要：选取合适的保养策略有利于提升直线加速器的多叶准直器的运动性能。将瓦里安Trilogy多叶准直器的叶片作为研究对象,依据保养策略分为试验组和对照组。基于保养前后,分别比较两组策略的叶片反弹测试和阻力测试。结果显示,试验组中的润滑脂清洁保养效果优于对照组中使用医用酒精清洁的效果,前者能够有效提升多叶准直器的运动性能,保障直线加速器的稳定运行。The selection of appropriate maintenance strategies is beneficial for improving the motion performance of the Multi-Leaf Collimator(MLC)of a linear accelerator.The leaves of the Varian Trilogy collimator were se-lected as the research object and divided into an experimental group and a control group according to the mainte-nance strategies.It compared the blade rebound test and resistance test of two strategies before and after mainte-nance.The result showed that the cleaning and maintenance effect of the lubricating grease in the experimental group was better than that of the medical alcohol cleaning in the control group.The former can effectively improve the motion performance of the MLC and ensure the stable operation of the linear accelerator.
