饱和蒸汽压

We also measured the effect on the vapor pressure of benzene produced by saturating benzene with either cyclopropane or chloroethane, anesthetics used in a previous study to demonstrate that their equilibration with benzene decreased the solubility of benzene in water.

我们还测量了用以前研究中用的麻醉药环丙烷或氯乙烷使苯饱和对苯蒸汽压的影响，以证实它们和苯的平衡使苯在水中溶解度降低。

The possibility of vapor lock was increased on engine because the low saturated steam pressure and the great latent heat of gasification.

试验结果表明，燃油的密度愈低(其粘性也愈低，饱和蒸汽压愈高)，其高空点火性能愈好。

This invention relates to a method and device for generating cold atomic beam. Said method includes heating hot atom source in vacuum chamber to form atomic saturated vapor pressure atmosphere, cooling hot atom by three-D MOT to below 200uk and trapped to form cold atomic cloud, by the quarter wave plate reflection mirror in MOT the laser radiation pressure being unbalanced to make cold atom emitting along said direction, four tape arranged straight line set with contrary current direction is set in atom beam emission direction, which makes the atom emitted to forward to obtain cold atom beam with low speed, large flux and small transverse speed, laser beam vertical with atom beam set in the direction of cold atom emitting for atom beam state preparation to realize state concordant emitted cold atom beam.

本发明涉及一种冷原子束产生方法和装置，该方法包括在抽真空的真空室内，加热热原子源，在真空室中形成相应的原子饱和蒸汽压气氛；采用三维MOT对热原子进行冷却，冷却到200μk以下，并被捕获形成冷原子云团；通过三维MOT中开小孔的四分之一波片反射镜，而使得在该方向上激光辐射压力不平衡，使冷原子沿此方向出射；在冷原子束出射方向上，还置有载有彼此电流方向相反的四根成锥形排列的直导线，从而原子出射时将在磁场的作用下，不会沿横向膨胀而向前射出；便得到了出射速度低的、通量较大的、横向速度非常小的连续冷原子束；同时在冷原子束的出射方向上，设置有与原子束垂直的激光束，用于原子束的态制备，实现态一致的出射冷原子束。

Of simplicity, the ELJP model predicts the VLE for HCFC/HFC as well as other weak polar binary systems accurately. However, its parameters are determined by fitting vapor pressure and liquid density data of the pure substance over a temperature range of interest, and are, therefore, temperature dependent.

其缺点是分子的势能模型未能直接反映分子的极性，其参数须随温度而变，且这些参数又是由纯物质的一系列饱和蒸汽压和液相密度的实验数据回归得到，故存在一定局限性。

The problems of the heat transfer equation of cloud drop growth were analyzed from chemical potential and principle of phase equilibrium of multi-component system. It was pointed out that Clapeyron equation was the result gained under the condition of rigid phase equilibrium. It only shows the linear relation between steam press and temperature at saturation state, and does not show that there is any thermodynamic process which can meet this equation.
