1·Using Markov renewal theory we obtain some indexes such as the system availability, failure frequency and reliability function.

利用马尔可夫更新理论，得到了系统的可用度，故障频度 和可靠度等各项指标。

2·The failure vector, failure frequency sequence, maintenance vector, and renovation sequence of repairable components were constructed.

构造了元件的故障向量、故障频率序列、维修向量和修复序列。

3·The manufacture level of domestic CNC machine tools is low compared to overseas advanced manufacture level mainly because for low reliability and high failure frequency.

我国数控机床制造水平与国外先进水平相比还有很大差距，主要反映在可靠性差、故障率高上。

4·Because applications in a WebSphere Virtual Enterprise environment can therefore lose their sessions without an explicit application server failure, the frequency of session loss can be much higher.

因为WebSphere Virtual Enterprise环境中的应用程序在没有显式应用服务器故障的情况下会因此丢失它们的会话，因此会话丢失的频率会高很多。

5·As the plane crossed state lines neither pilot realized the jet no longer was on the correct radio frequency and that controllers were growing worried about their failure to stay in contact.

飞机随后飞越了州界，两位飞行员都没有意识到飞机已经不在准确的无线电频率上，而地面塔台也对无法与飞机保持联系感到越来越担忧。

6·Inverters can also automatically event of the failure of the faulty electrical switch to the state of emergency frequency.

也可以在变频器发生故障时自动将发生故障的电机切换到工频状态应急工作。

7·The nature frequency of dither mechanism will drift when temperature is changing. And this may lead to dither mechanism failure in the extreme.

在抖动偏频激光陀螺的工作过程中，抖动机构的自然频率会随温度漂移，极端情况下可能导致机构破坏。

8·When this frequency is used to affect the organ with E-field radiation this may cause acute cardiac decompensation, renal failure or inadequate behavior.

当这些频率用于电磁辐射对器官的影响，可能会导致急性心功能不全，肾功能衰竭或行为不当。

9·Line grounding fault is the most frequency failure for distribution network, and is also the major problem that distribution network operation is faced with.

线路接地故障是配电网最频发的故障，也是配网运行面临的主要问题。

10·Objective To investigate the frequency dependent effects of amiodarone on ventricular electrophysiology in right ventricular rapid pacing induced congestive heart failure (CHF) canine models.
