| 1. | 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。 |
| 2. | The difference in pressure between the and - medium chambers deflects the diaphragm
和-介质室的压力差使膜片发生偏转。 |
| 3. | This deflection measured travel is transmitted to the pointer via a push rod causing a pointer deflection in proportion to the difference in pressure
偏转测量到的移动通过推杆传递到指针，使指针根据压差发生偏转。 |
| 4. | Goal function is to minimize the expense of trickle system ; the difference in pressure of drip line is thought as restriction condition ; we may obtain optimizing len gth of drip line by answering to the goal function
本文在灌水小区面积一定的情况下，以田间管网的造价与运行费用最小为目标函数，以毛管的压力差为约束条件，求得田间灌水小区内毛管的经济长度。 |
| 5. | During the passage of tornadoes or waterspouts , the direct impact of very strong winds and the difference in pressure between the interior and outside of a building can shatter weak structures , and even blow away trees and vehicles
涡旋中心附近的气压非常低，并且风力强大。卷风经过时，单薄的建筑物可能会抵受不住强大风力及室内室外的气压差而损毁，树木及汽车等会被吹起。 |
| 6. | Great difference in pressure for two flow made pressure wave system and it help to extend the delay time for gas in chamber , which increases combustion effusion . second , to increase combustion effusion , the inlet temperature of air and gas should be enhanced in the range of heat releasing in chemical reaction . third , the first work condition is unburned absolutely and the second work condition is burnt in shear layer of inlet and the end of down wall zone in straight segment
对于压力差很大的两股气流,所形成的压缩波系的结构可以增加燃气驻留时间,提高燃烧稳定性;为了提高扩散燃烧的效率,在保证能放热的化学反应温度范围之内,应适当提高燃气及空气的来流入口温度;燃气喷嘴应居于燃烧室轴线上,是改进超音速燃烧室结构的一种思路。 |
| 7. | During the passage of tornadoes or waterspouts , the direct impact of very strong winds and the difference in pressure between the interior and outside of a building can shatter weak structures , and even blow away trees and vehicles . there have been reports of small boats capsizing in nearby waters on encountering waterspouts
涡旋中心附近的气压非常低，并且风力强大。龙卷风经过时，单薄的建筑物可能会抵受不住强大风力及室内室外的气压差而损毁，树木及汽车等会被吹起。在海上曾经有小型船只遇到水龙卷而沉没。 |
