化工英语论文20xx字篇一：英文文章总结无机材料金属辐射损伤阈值陶瓷辐射损伤阈值聚四氟乙烯(PTFE:聚四氟乙烯) 在只有100 Gy的辐射剂量下就会退化后，因此，聚四氟乙烯在辐射环境中是被禁止使用的；在接受辐照以后卤化聚合物和碳氟化合物)释放腐蚀性化学物质如HCl（盐酸）和HF（氟化氢）无机材料辐射对塑料的影响同时，涂层涂料还受到α粒子的影响，并且损伤比γ辐射更严重。
粘合剂的辐射损害弹性体:在总剂量小于10 kGy的条件下，辐射损害不太可能发生，同时，一些添加剂如胺类和酚类也可以使弹性体免受辐射的影响。
辐射对润滑油的影响玻璃窗口：远程可视化操作的内部通过一个很厚的含铅窗口吸收辐射射线。
窗口玻璃上的辐射损失相机镜头：加固后的CCD相机的耐辐射范围从100 Gy —10 kGy。
光学纤维：即使低剂量的辐照也会引起光钎的光学衰减，经测试，商用光纤已经退化到100 dB /公里/ Gy。
但是，当纤维的核心不包含任何掺杂物质时，,衰减就会大大降低，这对经常用于传输信号的红外波段的光是十分重要的。
这种抗辐射加固后的光纤可以暴露在1MGy的环境后只衰减0.1 dB/m。
电子及电子元器件真空管：由于真空管的容量和对功率要求使得它很少在电子工艺中使用，但是，它是在一个非常高剂量率的辐射环境中可以工作的器件，它可以承受的总剂量为1MGy，为了避免总剂量和剂量率的影响，许多抗辐照摄像机中都使用了真空管。
