The Distribution Of Eigenvalue Of A Parallel Repairable System With Two No-identical Unit

The property of operator's rcsolvent of a parallel repairable system with two no-identicalunit is discussed in this paper. We randomly giveδ＞0 andγ=α+b,let's fixα₁ andα₂, Whichis satisfying to-μ+δ＜α₁＜α＜α₂. Therefore we get a conclusion is (?)||R(γ: A+E)||=0.And then we obtain that in the right place ofγ≥α₁ is composed of the finite isolatedeigenvalue corresponding spectrum of operators A+E system.
