By using linearoperatortheory in L2 space, we proved that the operators of this kind has not more than denumerable positive eigenvalues.
运用L2空间上的线性算子理论,我们证明了这类算子存在至多可数个正的本征值。

Basing on traditional operatortheory, operator madel for a circuit is established, and a new method for the solution of response of linear time invariance system is introduced.
