MTBF quite commonly appears as a non-functional requirement.

MTBF 通常作为非功能需求出现。

What are the expected availability, reliability, MTBF and Time-to-Repair?

预期的可用率、可靠性、平均故障间隔时间(MTBF)及修复时间怎样？

The mean time between failures (MTBF) for the controller of the system can be over 10 years.

系统用控制器平均无故障时间达到10年以上。

Its usage and cumulative flying time during this program showed an MTBF exceeding 5000 hours.

在该程序中的的使用和累计飞行时间显示的MT BF(平均故障间隔时间)超过5000小时。

The net effect of these tricks is to be able to generate MTBF Numbers measured in years in just a few weeks.

这些手段的净效应是能够在几个星期内生成几年中才能度量出的MT BF数字。
