| 1. | The dall flow tube is an empirical design with an extremely high pressure head recovery . Dall流量管是具有特别高的压头补偿的实验装置。 |
| 2. | The method involves measurement of the volume of liquid, under constant head conditions . 这个方法,液体在恒定的压头下,测定液体的体积。 |
| 3. | When the downstream head is greater than about 3/5 of the upstream head, flow is submerged . 当下游压头大于上游压头约35时,流量是潜流。 |
| 4. | It is frequently referred to as "pressure head" when expressed in terms of energy per unit weight of water . 当以单位水重的能量来表达时,经常看作为“压头”。 |
| 5. | Also, the difference in pressure between any two points in a bed is roughly approximated by the static head of bed between these points . 还有,床层中任意两点间的压差大致等于这两点间床层静压头。 |
| 6. | The simulation and manufacture of the end cap pressure sensor 端盖压头仿真与研制 |
