本文考虑了嵌镶晶体中经各级衍射的X射线的偏极化状态的变化，对次级消光效应作了较严密的处理。
Account is taken of the change in the state of polarization of multiply diffracted X-rays in Mosaic crystals, and a more rigorous treatment of secondary extinction is given.
受激射效应影响，消光比及频率啁啾在弛豫振荡频率处达到极大值。
Due to the lasing effect, the peak modulation frequency of extinction ratio and chirp occur at the relaxation oscillation frequency.
