压强差 meaning in English

p1-p2
pressure difference

Pitot tube allows an indirect measurement of speed by determining the dynamic pressure from the difference between the total and static pressure
空速管提供了一种间接测量速度的方法，它是通过测定全压和静态压强差值的动态变化来测量速度的。
The best spherical windows parameters are chosen according to rms of phase . stress - birefringence of laser windows is deduced by using index ellipsoid

Membrane distillation is an important branch of membrane separation technology which employees a hydrophobic microporous membrane for the separation process . during md process , feed contacts with one side of membrane , after water evaporates on hot side , vapor transfers to cold side under pressure drive , where vapor is condensed on cooling wall and then collected or removed
膜蒸馏技术是膜分离技术中的一个重要分支，它是指利用一疏水性的多孔膜，膜热侧与待处理液直接接触，待处理溶液中的水在膜热侧汽化后，气体在压强差的推动下，通过膜孔传递到膜冷侧，冷凝后收集或除去的一种分离技术。
