本文用量子力学中的密度矩阵算符理论导出了Pöschl-Teller势阱中的光整流系数的解析表达式.考虑到在Pöschl-Teller势阱中存在两个可调参量k和λ，并且势阱的形状随着k和λ取值的不同而明显不同，从而其光整流系数也发生相应的变化.因此我们可以通过调节k和λ的取值而获得Pöschl-Teller势阱中的光整流系数的变化规律，并找到其最大值，从而为实验提供必要的研究方向与理论依据.

Analytical expression of the optical rectification in thePöschl-Teller well is obtained by the density matrix method.Since there are two adjustable parameter k and λ in the Pöchl-Teller well and the shape of the well is changed with k and λ,the coefficient of the optical rectification will change with the parameter k and λ too.It can be obtained the variational rule of the optical rectification coefficient by adjusting the parameter k and λ.From the rule the maximum of the optical rectification coefficient can be got.
