研究由一个可靠机器,一个不可靠机器与一个无穷容量的缓冲库构成的系统主算子在左半复平面中的特征值,证明对一切θ∈(0,1),(2(λη_1μη_2)~(1/2)-λη_1-μη_2)θ都是该主算子的几何重数为1的一个特征值.
We study eigenvalues of the operator corresponding to the system consisting of a reliablemachine,an unreliable machine and a storage buffer with infinite capacity workpieces and prove that(2(λμ_1μη_2)~(1/2)-λμ_1-μη_2)θare eigenvalues of this operator with geometric multiplicity one for allθ∈(0,1).
