The enhancement of water vapor in compressed atmospheric air was measured at 30, 40, and 50 °C over respective pressure ranges of 10 to 35 bars, 15 to 60 bars, and 10 to 100 bars. The data for each isotherm were fitted by the method of least squares to an empirical smoothing equation of the form ln = where is the enhancement factor, is the total (absolute) pressure and and are constants. A detailed error analysis, necessary for the eventual use of the data in humidity standards work, shows that the calculated (predicted) values of have an estimated limit of systematic bias of ±0.07 percent and a maximum observed standard deviation of a predicted value of ±0.2 percent.
在30℃、40℃和50℃下，分别在10至35巴、15至60巴和10至100巴的压力范围内测量了压缩大气中水蒸气的增强情况。通过最小二乘法将每个等温线的数据拟合为形式为ln = 的经验平滑方程，其中 是增强因子， 是总（绝对）压力， 和 是常数。对湿度标准工作中最终使用这些数据所必需的详细误差分析表明， 的计算（预测）值的系统偏差估计极限为±0.07%，预测值的最大观测标准偏差为±0.2%。
