Via chemic technique calculate, we get the average molecular weight and saturationvapor tension, thereby, we calculate the volatility.
通过化学工艺计算，得到了各馏分的平均分子量和饱和蒸汽压，进而求出其挥发度。

Experimental results show that the condensation heat transfer coefficient of thermoexcel-C tube decreases as the saturationvapor temperature increasing.
实验结果表明：随着饱和蒸汽温度的提高，C管的凝结换热系数下降。

That is different from the elevation above sea level atmospheric pressure and water temperature at 20 degrees centigrade higher than the saturationvapor pressure.
