关于碳氢化合物混合物的声速数据由Wang和Nur[J.Acoust]展示。SoC。上午好。，2725年(1991年)]非常符合一个简单的混合规则(速度的体积平均)的预测。使用伍德公式和时间平均近似对相同的数据进行了重新分析。Wood的声速公式总是小于时间平均公式，而时间平均公式本身又总是小于简单的混合规则结果。虽然体积平均规则与1-癸烯和i-十八烯二元混合物的数据最符合，但所有这些公式与数据的一致性都在1%以内，因此，不可能使用该数据集来区分这些公式。对于六种多组份碳氢化合物混合物也发现了类似的结果。
Ultrasonic velocity data on hydrocarbon mixtures were shown by Wang and Nur [J. Acoust. Soc. Am. 89, 2725 (1991)] to agree quite well with the predictions of a simple mixing rule (volume average of velocity). The same data are reanalyzed using Wood's formula and the time-average approximation. Wood's formula for acoustic velocity is shown to be always less than the time-average formula, which is itself always less than the simple mixing rule result. Although the volume average rule agrees best with the data on binary mixtures of 1-decene and I-octadecene, all these formulas agree with the data to within 1% and, therefore, it is not possible to distinguish among the formulas using this data set. Similar results are also found for six multicomponent hydrocarbon mixtures.
