在1500 ℃和2200巴的温度和压力范围内，对液态Se及其含Na、Tl和Cl的稀混合物进行了电导率σ和热电势S的同时测量。Na、Tl和Cl的加入使低温下的σ显著增加。低温下液态硒的S值为大正值。通过加入Na和Tl，S的符号变为负值。通过加入Cl，S的符号保持为正，并且值增加。带电的添加剂上的液体硒的输运性质的影响进行了讨论与键合配置的变化。
The simultaneous measurements of conductivoty σ and thermopower S for liquid Se and its dilute mixtures containing Na, Tl and Cl have been performed in the temperature and pressure range up to 1500°C and 2200 bar. The addition of Na, Tl and Cl give rise to a substantial increase in σ at low temperatures. The value of S of liquid Se is large positive at low temperature. The sign of S is changed to be negative by addition of Na and Tl. By the addition of Cl the sign of S remains positive and the value increases. The effect of charged additives on the transport properties of liquid Se is discussed in connection with the change of the bonding configuration.
