| 1. | Ttff - time to first fix 首次定位时间 |
| 2. | Minimum positioning time 最小定位时间 |
| 3. | Fault localization time 故障定位时间 |
| 4. | To the 1 thousand images , the locating rate is close to 95 % and the locating holds about half second 针对这1000多幅照片,本算法定位正确率可达95 ,定位时间约0 . 5s 。 |
| 5. | The time of the daily positions varied to some extent in the older publications but remained fixed at 0000 utc after 1944 在较早期的刊物内,热带气旋的每日定位时间在某程度上还未统一。 |
| 6. | The time of the daily positions varied to some extent in the older publications but remained fixed at 0000 utc after 1944 在较早期的刊物内,热带气旋的每日定位时间在某程度上还未统一。 |
| 7. | The result showed that the open - loop controller and pid controller can reach 0 . 17um and 0 . 01um positioning accuracy respectively . by add former feedback in the pid controller the response time of step input reduced form 1 . 2s to 0 . 3s 通过给pid控制器增加前馈环节,使定位时间从1 . 2s降低到0 . 3s ,有效地提高了系统进行精密定位的动态性能。 |
| 8. | In the lamost ( large area multi - object fiber spectroscope telescope ) project , 4000 optical fibers are mounted on its focal plane which diameter is 1 . 75m . the positioning precision less than 40 microns , and positioning time less than 30 minutes Lamost天文望远镜工程需要在直径为1 . 75m的焦面上定位4000根光纤,定位精度小于40 m ,定位时间小于30分钟。 |
| 9. | Programs that run entirely in ram benefit from improvements in cpu speeds , but the runtime of program that page is likely to be dominated by disk seeks , and may run many times more slowly than cpu - bound programs 能够完全装载在内存中的运行的程序能够能从cpu速度提高得到提高,但是换页程序的运行时间主要由磁盘的查找定位时间所决定,并且可能比cpu绑定的程序运行慢很多倍。 |
| 10. | Conventional single - observer passive locating methods are low in speed and precision . moreover , corresponding locating precision is sensitive to direction measurement errors , which puts forward high demands on measurement equipments impersonally 传统的单站无源定位方法总的来说具有定位时间较长、定位精度较低的特点,并且定位精度对方向测量误差非常敏感,在客观上对测量设备提出了较高的要求。 |
