| 1. | When viscous forces predominate the flow is proportional to the pressure drop across the element .
当粘滞力起主导作用时，流量当通过主要部分的压力降或正好。 |
| 2. | I dropped across an old friend in town today
今天,我偶然在城里遇到一位老朋友。 |
| 3. | I dropped across this old photograph in the back of the drawer
我偶然在抽屉的后面发现了这张旧照片。 |
| 4. | Read the pressure drop across the valve with a watts series pg meter
利用美国瓦茨系列pg仪器读出通过阀门的压降。 |
| 5. | In line design minimizes pressure drop across the valve thereby assuring maximum pump performance
直线结构将通过阀门的压降减小到最小程度，从而保证泵性能的最优化。 |
| 6. | 11 unless higher flooding is specified , trayed columns shall be designed for flooding up to the bottom tray and for pressure drop across the trays
除非规定了更高的溢流/冲洗,盘式塔的设计应利于溢流/冲洗至底盘和压力降穿过底盘。 |
| 7. | Crane globe valves are highly efficient for services requiring frequent operation and throttling when pressure drop across the valve is about 20 % of inlet pressure
当通过阀门的压降为管路压力的20 %左右时，美国克雷恩截止阀就能够高效应用在频繁操作和节流的应用场合。 |
| 8. | In 2007 , the minimum entry points dropped across the board in many colleges to 345 , in the case of ucd and 340 for ucc , with other colleges being somewhat higher
2007年全国许多大学的最低入学分数线降到了345分，象都柏林大学，科克大学是340分，其他一些大学要高一点。 |
| 9. | If the qsc device implements current limiting , the excessive current would combine with the potentially large voltage drop across the pass transistor to generate unwanted heat within the handset as well
Qsc器件实现电流限制，过多的电流会和潜在地大压降结合起来，通过晶体管产生不必要的发热。 |
| 10. | Not a mean village closed upon him , not a common barrier dropped across the road behind him , but he knew it to be another iron door in the series that was barred between him and england
他明白，每一个不起眼的村落在他身后关上的大门每一道落下的普通的路障都是一道横亘在他和英格兰之间的铁闸。 |
