摘要

采用Ｘ光透镜替代单色仪双聚焦镜应用于生物蛋白大分子晶体衍射分析，照射晶体样品的光强提高１—２个量级，衍射强度的提高远大于５倍，大大缩短了测试时间，分辨能力改善０．０２－０．０６ｎｍ，信噪比也有改善。

Abstract

By using monolithic X-ray lens

the direct beam intensity irradiating on crystalwas 1 to 2 order of magnitude higher than the traditional method with the doublefocusing mirrors. The diffracted X-ray intensity was increased by about 5 tAnes

andthe resolution was improved by 0.02 - 0.06nm . The signal to noise ratio was alsoimproved

and the time of measurement was reduced.
