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

1.结果表明，硅X吸收曲线决定硅制三沟道BCCD不在X区实现多谱成像。

2.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.

2.通过理论分析，找出证BCCD在X区工作衬底材料所应满足吸收曲线。
