我们已经观察到临界波动表现在两个不混溶的金属二元液体，Li-Na和Bi-Ga的临界温度以上的亚导电性。这种反常是在其他金属临界系统中观察到的一般形式。在这些系统中存在可测量的亚导电性，而在Ga-Hg系统中不存在亚导电性，这归因于Li和Na以及Bi和Ga的原子体积与Ga和Hg相比存在较大差异。
We have observed critical fluctuations as manifested in paraconductivity above the critical temperature in two immiscible metallic binary liquids, Li-Na and Bi-Ga. The anomaly is of the general form observed in other metallic critical systems. The presence of measurable paraconductivity in these systems and its absence in the Ga-Hg system is attributed to the larger differences in atomic volumes of Li and Na and of Bi and Ga as compared with Ga and Hg.
