摘要
本文研究了板几何中一类具各向同性、连续能量、非均匀介质和非对称散射裂变核的迁移算子A的谱,证明了这类算子A在带域Pas(A)中无复本征值等结果。
In fhis paper , we research the spectrum of the transport operator with isotropic, continous energy, nonhomogeneous and unsymmetric scattering kemel in slab geometry, and prove the results that the transport operator A has no complex eigenvalues in trip Pas(A), and so on.
