Complementarity of cool reserve system reliability's mathematics model

Establishing cool reserve system reliability's mathematics model is of important practice value in the design, forecast mechanism, electron system etc. The kinds and numbers of reason of system exerts on direct effect on establishing correct mathematics model when mathematics model is established. The paper complements traditional cool reserve system reliability's mathematics model by considering a kind of new system invalidation model, making system reliability model more perfect and this is proved by examples. Establishing right mathematics model is important for assuring production quality.
