摘　　要：文中介绍了用工业CT无损检测对多材质构件进行密度量化检测的方法.简要分析了电压、探测器灵敏度系数、扫描厚度、增减组分等不同检测参数对透射射线强度和各组分CT值的影响以及与构件各组分密度的关系.并以纤维增强复合材料构件作为实际例子,介绍了用工业CT成功测量构件内部材料密度的原理、方法及注意事项.This article introduced the method for testing the component density of multiple materials structure （MMS） quantitatively with ICT. The relation among each structure component density and the CT values and the every kinds of testing factor such as the voltage, the sensitivity coefficient of the detector, the scanning thickness, increase or decrease the part et al was analyzed briefly. By taking the test of fiber reinforced composite structure as an actual example, the principle, the method and the notice items during measuring the component density in structure by ICT were introduced.
