摘要：
The quantum mechanical version of Ewald's extended dynamical theory of diffraction is used for the study of the transmission and reflection of neutrons by a crystal. It is shown that the total reflection of neutrons at grazing incidence on a crystal is formally equivalent to the total reflection at the Bragg reflection position. Ewald's quantum mechanical and Fresnel's classical formulae for reflection and transmission at grazing incidence are compared.
