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光区工作衬底材所收曲线。

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光收曲线决定了硅制三沟道BCCD不能在X光区实现多光谱成像。
