摘要：
In this paper, by introducing an error estimate parameter eta and analyzing the magnitude of each term of the propagation equation, the propagation equations of amplitude and phase of x-rays can be obtained in the laser-produced plasma. It is found that the change of phase is only dependent on the electron density, and the change of amplitude is directly dependent on phase. Moreover, only if eta < 1, by using iterative approximation, the approximate solutions of phase and amplitude can be obtained. Finally, by computer simulation these solutions are confirmed.
