求翻译：Radiography is a method used for non-destructive inspection based on the differential absorption of penetrating radiation through the sample being inspected. Due to differences in density and variations in thickness, or even differences in absorption characteristics caused by variations in material composition, differe是什么意思？ 待解决

摄影是一种用于基于穿透辐射通过抽检的差分吸收的非破坏性检测方法。由于密度的差异和变化的厚度，或甚至由物质组成的变化引起的吸收特性差异，同一样品的不同区域会吸收不同量的辐射。此差分吸收的辐射可以检测到通过一部电影或甚至从电子检测器测量出来。这个采煤量被吸收的辐射效应影响将表明 th e 材料内部缺陷的存在，因此工业射线照相用于体积缺陷检测精度 （柯达，1980年）。
