The text analyses the reliability of the temperature automatic control system of cooling water in ships diesel engine,and by computing the reliability of all the system and the sub-system,we can conclude the improved way of this system,at the same time it puts forward that simple parallel reservoir of system is the useful way of improving reliability.

Approximate confidence limits of the reliability performances for cold standby series system based on progressively type-Ⅱcensored tests;

Empirical Bayes Approximate Confidence Limits of the Reliability Performances for Cold Standby Series System;

We firstly give Bayes estimators of the parameter and reliability performances;secondly, two-sample prediction intervals for future observation are obtained using Bayesian method;in the end, we research on the cold standby series system and derive the approximate confidence limits of the reliability performances.

For the sub-6-degree of freedom(DOF)parallel kinematic machines(PKM),it is necessary to separate the geometric error sources which influence the compensable and uncompensable errors of the mobile platform by error modeling,so as to supervise the accuracy design and kinematics calibration.

It is significant for the design and application of parallel manipulators to study the static and dynam-ic performance of parallel kinematic machines.
