| 摘 要： | 通过实验测量，对石墨悬浮液进行热导率和黏度系数的研究。采用不同的超声时间，从而获得不同大小颗粒的石墨悬浮液。在不同的超声时间下得到了石墨悬浮液的热导率随体积分数的变化规律，并对其热流逾渗现象进行了分析。同时，对于室温下的石墨悬浮液进行了黏度系数的测量，可以得到石墨悬浮液的逾渗点的导热性质和黏度性质的对比，从而得到了两者是截然相反的结论。

| Abstract: | Thermal conductivity and viscosity of graphite suspensions were experimentally studied by transient hotwire method and ARG2 method, respectively. By choosing different sonication time, thermal conductivity of graphite suspension at different volume fractions were obtained, as well as a thermal percolation behavior was observed. The viscosity shows opposite trend compared with thermal conductivity near percolation regime, which increases much faster before percolation than after percolation. |

| Keywords: | thermal conductivity dynamic viscosity suspension percolation |
