工业CT在铀氢化物密度测量中的应用

Application of Industrial Computed Tomography in Density Measurement for Uranium Hydride

采用模拟试验的方法,对试样的铀床进行了重复的吸氢-释氢试验。通过测定已知密度标准试样(铀床壁为不锈钢)的CT值,建立CT值和密度之间的线性关系,测定铀床内铀氢化物的CT值,得到其不同截面的密度分布曲线。

Simulation test method was used to absorb hydrogen and discharge hydrogen repeatedly in container which installed test objects.By measured CT number of stainless steel which has known its density and found linearity relation of CT number and density,the density curve of different section was obtained by measuring the CT number of uranium hydride in test container.
