3. Her mistakes looked easily reparable in the light of her restored self-confidence .

4. On the other hand, using cast post is suggested to increase the fracture strength and prevent non- reparable failure under reduced bone condition.

5. The Markov method is used to analyse the reliability of dual hot - redundant reparable fault tolerant control system, and some calculating formula are derived.

6. This paper deals with the reliability computation of a reparable system of which the main unit possesses priority both in operation and maintenance.
