摘　　要：在傍轴近似下将等离子体中Ｘ光传输的波动方程写成Ｓｃｈｒｓｅｄｉｎｇｅｒ方程的形式，利用量子力学的进化算子得到衍射积分的一般形式，在光学薄近似下研究了Ｘ光激光干涉法所测得的位相与等离子体密度的关联。In this paper, the Maxwell equations of X-ray laser beam through stationary plasma waswritten as the equation in the form of time-dependent Schroedinger equation (TDSE), the generalizedHuygens' integral was derived in terms of evolution operators from the viewpoint of quantum mechanics forthe first time, and the analytical relationship of the electron density of plasma with the phase difference of theX-ray through stationary plasma with gain and the same X--ray through vacuum under the optical thin approximation (its diffraction effects are negligible).
