| 摘 要： | 采用改进的阿基米德法对Ga熔体的密度值进行了升温和降温过程测定分析.试验结果表明,升、降温时Ga熔体的密度值在熔点附近都出现异常变化,出现了热缩冷胀的现象,并讨论了密度值变化对黏度特性的影响.从熔体液.液结构转变的角度,对密度的不连续性进行了分析讨论.

| Abstract: | The densities of Ga melt were, positively and negatively, measured by an improved Archimedean method. Results show that densities of molten Ga changes extraordinarily near the melting point during the temperature increasing or reducing, with heating expansion and cooling contraction. And the influence of the density change on the viscosity character was discussed. Finally the discontinuous variation of density was discussed from the point of liquid-liquid structure transition. |
