By use of a new type double circulation ebulliometer, Isoplethic VLE data were determined under 15 different concentrations for the system ethanol-n-hexane in a temperature range from 298K to 331K. Isothermal VLE.

由等组成数据，可方便地求算该混合物在所测温度范围内的微分汽化热和饱和蒸气压，进而推算过量自由烩和等温汽一液平衡数据l：。

However, manifolding may not be adequate if ambient temperature conditions do not yield sufficient heat flow or product vapor pressures within the containers.

但是，如果周围温度条件不能产生足够的热流或容器内的蒸气压，并联就没有作用了。

Nine thermodynamic properties, combustion enthalpy, evaporation enthalpy, liquid enthalpy and heat capacity, vapor heat capacity, thermal conductivity, kinematic viscosity, density and vapor pressure, are predicted or correlated with satisfactory results by using a simple hypothesis of the groups for petroleum fractions.

简单的基团假设，可以定量地预测和关联石油馏分燃烧焓、汽化焓、液体焓与热容、汽体热容、热导率、运动粘度、密度和蒸气压等9种热力学性质，效果满意。

In order to determine the saturated vapor pressure of colloid ed dinitrogen tetroxide,and find out its change rule with the various temperature,a testing equipment of determining satuated vapor pressure of colloid ed dinitrogen tetroxide was designed and constructed according to the principle of static testing.

为了测定胶体四氧化二氮的饱和蒸气压，找出其在不同温度条件下的变化规律，采用静态法测试原理，自行设计建立了四氧化二氮胶体饱和蒸气压的测试装置，测得了常压下液体和胶体四氧化二氮的饱和蒸气压数据，结果表明，四氧化二氮体系成胶后比成胶前的饱和蒸气压略有降低，且温度越高其差值越大。

At 70 F hydrogen chloridehas a vapor pressure of 613 psig.

氯化氢在70 F的蒸气压为613 psig。

It exhibits a vapor pressure of 613 psig at 70oF.

在70oF时，它的蒸气压是613psig。

Times the vapour pressure at 50℃ of the liquid to be transported, minus100kPa but with a minimum test pressure of 100kPa

不小于待运液体在50~C时的蒸气压的1.75倍减去100千帕，但最小试验压力为100千帕

Thermogravimetric analysis was extended to the measurements on vapor pressures of three n-alkanes, hexadecane, heptadecane and octadecane, on the basis of the Langmuir equation for zero-order vaporization process. The vapor pressures were calculated by two different methods, a constant-parameter one and a comparative one, from the TGA data. These results are in good agreement with the reference data calculated from the Antoine equation.

根据自由蒸发过程的Langmuir关系，将热重分析用于正十六烷、正十七烷和正十八烷等3个正构烷烃的蒸气压测定，分别采用常数法和比较法计算蒸气压，其结果与文献数据符合较好。

According to the change of the kinds of elements content in slag, F in slag volatilizes in the form of KF and NaF, KF volatilizes much more easily than NaF, KF plays a leading role in the F volatilization, theoretical analysis shows that the saturation vapour pressure of KF in the test slag is 31. 4 times of NaF; when F content is far more than K, KF volatilization is first order grade reaction, it is dominated by K content, the apparent activate energy is 275. 30KJ/mol.

4依据对含氟熔渣中高温条件下（1450℃、1505℃）的各种元素含量的变化情况，发现氟在熔渣中是以碱金属氟化物挥发，并且，KF比NaF具有更好的挥发性，在氟的挥发中占主导地位，理论研究也证明，在1505℃试验组成的熔渣中，KF的饱和蒸气压是NaF的31.4倍；在含氟量远大于钾含量的情况下，KF挥发为一级反应，受钾浓度控制，其表观活化能为275.30KJ／mol。
