1. Waiting outside means wasting useful time.

2. Extremely long useful time, low overall operating costs.

3. Most people who want to get ahead spend useful time writing personal notes of gratitude, sympathy and congratulations.

4. In order to improve the useful time of distribution chute of larger blast furnace, design principle and the effect on distribution rule caused by chute structure parameters were discussed.

5. The structure reliability is high , useful time is long , it is the essential step for extending the whole furnace life.

6. The effects of the useful time and the distance between the light source and detected site on the results of measurement were discussed in detail.

7. If these are all examples of attempts to convert "down time" into useful time, take note of the way in which "down time" has been expanded.

8. Then proposes three ways to enhance the security of 802.1X like adopt EAP-TLS, add status confirmation and set useful time for certification.

9. Starting directly will produce a big current impact and short the useful time of the motor.

10. This thesis develops a kind of constant flow blanking plug with simple structure, long useful time and low costs.

11. In order to study the relation between structural parameters and work efficiency or useful time, a nonlinear dynamics model of a load was presented for air drilling motor.

12. Using the optical temperature control accessory, silica peak height signal was enhanced doubly, reducing atomization time, extending useful time of graphite tube.

13. In this specific case, without a fork, the Android project would have had a hard time achieving its goals (with regard to power management and more) in a commercially useful time.

14. The installation software is protected by SN and warns for unregistered copy useful time limitation.

15. The reliability of GM counter tubes should be described by useful time before failure life and failure rate during life.

16. As with all dead things, holding onto it won't keep it alive or change the fact that it's useful time has come and gone.

17. The fluorine mixed gas prepared by this device, which may prolong the working hours of excimer-laser 2 to 3 times and prolong the average useful time of lens of laser 3 to 5 times.

18. The discharging board is dimidiate structure, with electroplating hard chrome on the surface. It is easy to be repaired and lengthen the useful time.

18. try its best to gather and build good sentences.

19. Pattern of Success Most people who want to get ahead spend useful time writing personal notes of gratitude, sympathy and congratulations.

20. These new methods can be practiced as a real-timedownhole gas influx detection technique during drilling process, and can save useful time fordealing with blowout and other well troubles.
