流量

• Two different methods may be used to measure flow rate; instantaneous and integrating .
  流量可用瞬时和累计的两种不同的方法进行测量。
• 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。
• 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。
• A sample size needs to be established when this method of mass flow measurement is used .
  在使用这种质量流量测量方法时，需要测定试样的大小。
• In the lobed impeller the measuring chambers are the space between the lobes and the meter housing .
  叶轮式测量室是叶轮和流量叶壳体间的空间。
• It is not clear whether secretory stimulants directly influence the flow of blood to mucosa .
  分泌的刺激物是否直接影响胃粘膜的血流量还不清楚。
• The inertance is the tendency of the fluid to resist flow rate changes due to pressure forces .
  惯性是流体阻碍由于压力而引起的流量变化的倾向。
• Deposits of foreign materials will change the sharp contours which govern its coefficient of discharge .
  杂质的淤积会改变决定流量系数的轮廓形状。
• Techniques borrowed from the ring laser gyro can be adapted to fluid flow measurement .
  借环形激光陀螺仪的技术，加以改进使之适用于流体流量的测量。
• The marginal propensity to import, in other words, is a "leakage" from the expenditure stream .
  换言之，边际进口倾向是支出流量中的一个“漏出量”。
