摘　　要：在Ｇａ的Ｋ吸收限附近的强反常散射条件下，测定了ＧａＡｓ（６００）对称Ｂｒａｇｇ情况的衍射波和透射波的摇摆曲线，并将其和Ｘ射线衍射动力学理论的相应计算结果作了比较。The diffracted and transmitted rocking curves for GaAs(600) in the symmetric Bragg case have been measured under the condition of extremely anomalous scattering near the Ga K absorption edge, and then compared with the corresponding results calculated in the dynamic theory of X ray diffraction. We have thereof pointed out that the transmitted rocking curves near the atomic absorption edge in Bragg case are useful in the study of anomalous scattering.
