- How do you change Greenwich mean time to Beijing time? 怎么计算格林尼治时间对应的北京时间?
- The mean time to repair (MTTR) is one of the main indexes for system's reliability analysis and risk analysis. 串联系统的特点是串联元件中任一部分（元件）失效都可导致系统失效。
- Also the temperature, current density, stress gradient and alloy elements have strongly effects on MTF (mean time to failure) of electromigration. 温度、电流密度、应力梯度、合金元素及工作电流模式等也对电迁移寿命有重要影响。
- Reliability of each individual node is enhanced by reducing its MTTR (Mean Time To Repair).Therefore, the availability of the whole system is improved. 通过测试和分析，这种快速的自动恢复机制通过缩短单结点的平均修复时间MTTR而提高了单结点的可用性，从而也提高了整个系统的可用性。
- I need some time to orient my thinking. 我需要一些时间来使我的思想适应。
- A transistorize radio takes no time to warm up. 晶体管收音机不需要预热时间。
- The individual parameter for evaluating overhauled motor vehicles are: mean time to first failure(MTTF),mean time between failures(MTBF),equivalent failure rate(D),ect. 可靠性单项指标的确定 :平均首次故障里程 (MTTF) ,平均故障间隔里程 (MTBF) ,当量故障率 (D) ;
- Mean time to data loss is similar to MTBF for disks and tapes, but is likely to differ in RAID arrays, where redundancy can protect against data loss due to component failures. 对于磁盘和磁带设备来说，平均数据丢失时间的概念与MTBF相似，但是对于RAID阵列来说，平均数据丢失时间可能与MTBF不同，这是因为在RAID中，冗余性能够保护组件故障条件下数据丢失情况的发生。
- It may take a long time to find a solution to the problem. 也许要花很长时间才能找到解决这个问题的办法。
- However, there was significant heterogeneity in these trials, and the mean time to complete resolution was inconsistent across trials, precluding pooled analysis. 不过，这些试验有显著的异质性，各试验中，达到完整缓解的时间也不一致，而无法汇整分析。
- It took him long time to smooth away perplexities. 他花了好长时间才消除了困惑。
- It is time to pony up on that bill. 是照帐付钱的时候了。
- My explanation took a long time to sink in. 我的解释很久才被人理解。
- He does odd jobs for me from time to time. 他有时给我干点零活。
- We're just in time to catch the train. 我们正好赶上了火车。
- I think the trip may give me time to simmer down. 我以为这次旅行会给我时间冷静下来。
- He does the odd job for me from time to time. 他偶尔来为我做些零碎的工作。
- It's only a waste of time to speak to her. 和她说话纯粹是浪费时间。
- There were also no significant differences between the procalcitonin and standard-therapy groups in terms of the exacerbation rates, need for rehospitalization, or mean time to the next exacerbation. 考虑到加重速率，就是需要在住院或者下次加重的平均时间，原降钙素组和标准治疗组之间也没有明显区别。
