通过统计10年的维修故障记录数据 ,使用相关性分析和曲线拟合的方法 ,观察器件故障与直线加速器系统、运行时间、维修耗费的关系 ,发现了一些器件故障以及维修耗费的特点 ,并提出了相应的应对措施
Through statistical analysis of 10-year maintenance failure record data, correlation analysis and curve fitting method were used to observe the relationship between device failure and linear accelerator system, operation time and maintenance cost, and found some characteristics of device failures and maintenance costs. The corresponding response
