The results show that the silicon three-channel BCCD can not realize multi-spectral imaging in the region of X-ray.

结果表明，硅对X吸收曲线决定了硅沟道BCCD不能在X区实现多。

Based on the result of theoretical research the absorption coefficient curve of a substrate material has be ound,which ensure the three-channel BCCD work in the region of X-ray.

通过理论分析，找出了能保证BCCD在X区工作衬底材料所应满足吸收曲线。
