我们证明相对论维里定理，这定理对于连续谱空间里本征值的缺乏给出了简单的标准。

We prove the relativistic virial theorem, which gives simple criteria for the absence of embedded eigenvalues in certain regions of the continuous spectrum.

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。

By using linear operator theory in L2 space, we proved that the operators of this kind has not more than denumerable positive eigenvalues.
