摘要：

The electronic resistivity and thermopower of liquid InSb as a function of temperature have been measured using the d. c. four-probe method and also from the electromotive force produced by the temperature gradient. Abnormal behavior is observed and more accurate data are obtained. For liquid InSb, the temperature dependence of resistivity increases with temperature near the melting point, and almost is constant when the temperature is above 716°C. The abnormal behavior has also been found in the temperature dependence of thermopower almost at the same temperature. Based on other physical properties changing with temperature and the structure of liquid InSb near melting point, the result obtained in this work suggests that the liquid structure of InSb may be changed at 716°.
