Abstract
From the theory of quantum mechanics,we studied higher-order effect that radiation field interacts with medium,and got the equation of kinematics of density matrix that medium had excitation in radiation field. From this ,we got the calculating formula when radiation reached saturation.We also got an important conclusion that intensity was in inverse proportion to the square of transition speed and in direct ration to attenuation speed of high and low energy level.
