摘要
利用δ－函数按标量波函数系的正交完备展开式直接推导出δ－函数按矢量波函数系的正交完备展开式。由此说明数字矢量函数空间可以通过它在矢量波函数系上的射影分解为三个不相交的子空间。
n this paper, it is shown that the orthocomplete expansion of δ-function in the set of vector wave functions can be derived by using the orthocomplete expansion of δ-function in the set of scalar wave functions. Thus it is concluded that a vector function space can be resolved into three subspaces which do not intersect each other through its projection on the vector wave function set.
