关于格林函数对称性讨论

摘要

Green＇ s function is not only an important method in mathematical physics equations, but also a tool which must be mastered by the physics majors. This paper, based on the physical scenario, discusses the physical meanings of Green＇s function and certificates the symmetry of Green＇ s function in three detailed ways. This is helpful to the understanding and flexible applica- tion of Green＇ s function.%格林函数法是数学物理方程中的一种重要方法,同时也是物理专业学生必须掌握的一种方法.以物理情景为依托,阐述了格林函数的物理意义,并对格林函数的对称性作了三种详细的证明.这将有助于理解和灵活地应用格林函数.
