摘　　要：预防X线管损坏对最有效使用X线管、延长X线管寿命有重要作用。本文通过对如何预防X线管阴极损坏、阳极损坏的各种方法进行分析,得出以下经验:在实际操作X线设备中,必须正确应用X线管的负载曲线与生热冷却曲线;在维修或操作X线设备中,X线管灯丝不可过热,且避免不必要曝光,同时严格遵守规则,正确操作;每次曝光后,应有足够的冷却时间;不得碰撞X线管管套。Effectively preventing the X-ray tube from damage plays an important role for X-ray tube to be effective use and extend its life. Through analyzing the ways of how to prevent the damages from X-ray tube cathode and anode, we obtained the following as advises. In actual operation of X-ray equipment, the operator should correctly use the load curve and heating-cooling curve. In the maintenance and operation of X-ray equipment ,operator should pay attention not to overheating the X-ray tube filament, avoid it from unnecessary exposure,and regulate specifications and operate properly. As soon as the X-ray tube filament complete exposure, operator is better to persist the gap as cooling time. And the X-ray tube sets do not be crashed all the time.
