气压

• Fixed cistern barometers are used as a standard for checking altimeter .
  固定槽式气压计可以作为标准件去检验测高计。
• Fixed cistern barometers are used as a standard for checking aneroid barometers .
  固定槽式气压计可以作为标准件去检验无液气压计。
• The carrier gas is supplied to the instrument at constant pressure from a cylinder .
  载气一般由压缩钢瓶供给，并要使载气压力恒定。
• A barometric altimeter indicates height above sea level or some other selected elevation .
  气压高度表用以指示海平面或另外某个被选定高度以上的高度。
• The presence of a nonvolatile solute in a liquid always lowers the vapor pressure of the solution .
  溶液中存在的非挥发性溶质，总是使溶液的蒸气压降低。
• The most accurate observations are made when we observe the light emitted when the vapour pressure is low .
  当蒸气压很低时，可以对原子所发射的光谱作出最精确的观测。
• If the burst duration is too long, or the gas pressure too high, the bubbles tend to collect and rise in columns .
  如果放泡时间太长或气压太高，气泡将聚在一起以气柱状上升。
• The vapor pressure and heat of vaporization have been shown to be significant properties in nonsteady droplet vaporization .
  在非稳态的液滴汽化中，蒸气压和汽化热是重要的性质。
• A nearly ideal solution like benzene-toluene shows a vapor-pressure curve that conforms very closely to the plot .
  象苯一甲苯那样的接近理想溶液，其蒸气压曲线与此图板极为吻合。
