mean time to repair

To satisfy these requirements, either MTBF ( Mean Time between Failures) is lengthened or MTTR ( Mean Time to Repair) is shortened.

要满足这一要求，一方面延长平均无故障时间MTBF，另一方面缩短排除故障修理时间MTTR。

By concentrating on Mean Time to Repair ( MTTR) rather then Mean Time to Failure ( MTTF), we find that quick recovery reduces recovery time and thus offers higher availability.

通过关注平均修复时间，而不是平均故障时间，发现快速的恢复减少了恢复时间，因而提供了更高的可用性。

The calculation result shows that mean trouble free time in the two gas well gathering station system is 18 days. The fault happens 20 annually, 82% of which has happened because of dehydrating plants, and mean time to repair is 46 hours.

计算结果表明，集气站平均无故障工作时间18d，每年约发生20次故障事件，其中82%的是由脱水装置故障引起的，且每次故障持续约46h。时间（英文）

Finally obtain the mean time between failures ( MTBF), mean time of repair failures ( MTTF), inherent availability ( A) as well as reliability index such as reliability and failure rate function according to the distribution model.

最后根据分布模型计算得到该加工中心的故障间隔时间（MTBF）、平均维修时间（MTTF）、固有可用度A以及可靠度和失效率函数等可靠性指标。

These cheap methods of self-recovery in the article are new approach to high availability and reliability, extend the time to failure and shorten mean time to repair.

实验结果表明，本文所提到的软件自恢复策略是一种具有高可行性和可靠性的方法，这种方法延长了软件的失效时间并且缩短了软件的修复时间。

MTTR ( Mean Time To Repair) is a key quantitative index to describe the maintainability.

平均修复时间MTTR（Mean Time to Repair）是衡量维修性的重要定量参数。

As an important quantificational index for maintainability, the predication method and algorithm of mean time to repair ( MTTR) are always dependent on experimentation and experience.

平均修复时间（MTTR，Mean Time to Repair）作为一个重要的维修性定量指标，目前其预计方法及算法立足于大量的试验结果和经验估计。

The mean time between failure ( MTBF) is 449 hours, and the mean time to repair ( MTTR) is 22. 1 hours. ln its subsystems, the MTBF of tool post is smallest and that of electric system is biggest;

平均无故障时间MTBF为449h.平均修复时间MTTR为22.1h.各子系统中，方刀架的可靠性最好，电器系统的可靠性最差；

In research, back-end nodes in the cluster-based Web server are took as the research object. The research goal is to improve the availability of the back-end nodes by reducing their MTTR ( mean time to repair).

以Web集群服务器的后端节点作为研究对象，通过减少后端节点的MTTR（Mean Time to Repair），来提高它们的可用性，从而提高整个集群服务器的可用性。
