摘要
讨论了具有两同型部件的冷贮备可修复系统,首先证明系统算子可以生成正压缩C0半群T(t);接着证明了T(t)是拟紧算子,且0是对应系统的主算子及其共轭算子的几何重数与代数重数为1的特征值.由此推出:该系统的时间依赖解,当时间趋向于无穷时,以指数形式收敛于系统的稳态解.
It was discussed a cold standby repairable described by a group of partial equations with integral system with two identical components. The system were boundary conditions. Firstly, it was showed that the operator corresponding to the system generated a positive contraction C0-semigroup T（ t ）, and proved that T{ t ） was a quasi-compact operator. Secondly, it was verified that 0 was an eigenvalue of this operator and its adjoint operator with geometric and algebraic multiplicity one. Lastly, by using the above results, the time- dependent solution of the system strongly converged to the steady-state solution was established.
