全文分为二部分，第一部分研究时空域衍射理论和算子光学方法，及其在激光光学和强激光技术中的应用。

Part I deals with the diffraction theory in the time -space domains and operator optical methods, as well as their applications to laser optics and high power laser technology.

同时也刻画了布尔代数上强保持交换矩阵对的线性算子。

And also we characterize the linear operators that strongly preserve commuting pairs of matrices over Boolean algebras.
