Abstract
Some studies are carried out on the diffraction characters of perfect bragg crystals in reflectivity with the dynamical theory of x-ray diffraction,some figures of the diffraction intensity distribution are given,and some calculations are given for the integral reflection intensity and the width of the diffraction intensity distribution.The results show that the diffraction intensity distribution with the same energy,the integral reflection intensity and the width of the diffraction intensity distribution with the same bragg angles are different for different crystals,and a fast increase of the integral reflection intensity and the width of the diffraction intensity distribution when bragg angles are larger than 45°.
