抱歉,你是對的。
Mean time before failure是 MTTF~
http://www.relex.com/resources/mtbf-mttf.asp
"Mean time before failure" is a reliability calculation, often referred to as
Mean Time To Failure , or MTTF.
"Mean time between critical failure" is often simply called Mean Time Between
Failures, or MTBF.
MTTF Versus MTBF
MTBF (mean time between failures) is the expected time between two successive
failures of a system. Therefore, MTBF is a key reliability metric for systems
that can be repaired or restored. MTTF (mean time to failure) is the expected
time to failure of a system. Non-repairable systems can fail only once.
Therefore, for a non-repairable system, MTTF is equivalent to the mean of its
failure time distribution. Repairable systems can fail several times. In
general, it takes more time for the first failure to occur than it does for
subsequent failures to occur. Therefore, MTTF for a repairable system can
represent one of two things: (1) the mean time to first failure (MTTFF) or
(2) the mean uptime (MUT) within a failure-repair cycle in a long run.
