摘　　要：在ABCD矩阵基础上 ,通过引入角度色散项获得了可以方便描述色散系统的 3× 3阶矩阵方程 利用这种矩阵方程计算了消像差光栅展宽器中的二阶色散量 ,得到的结果与由常规积分法获得的结果相同 ,表明采用矩阵方程计算色散系统色散量具有简单方便 ,包含信息量大 。A 3×3 order matrix formalism for describing dispersion system conveniently is achieved by introducing an angular dispersion term based on WTBXABCDW matrix formalism. The matrix formalism is used to compute the second order time dispersion of the aberration-free stretcher. The same conclusion as the one achieved using the way of routine integral and ray trace is obtained. It is proven that computing the time delay dispersion of any dispersion systems using matrix formalism not only is convenient but also can offer more information about systems. In addition, this way is suitable for any dispersion systems.
