| 摘 要： | 本文采用Bose量子统计方法,对地幔矿物的激子热传导问题进行了详细讨论,得到了激子热导率K_(ex)的表达式,并指出在高压和高温下,激活能A对激子热导率的变化速率有重要影响。讨论结果表明,激子热传导作用有可能在下地幔发生,但它却不是热传导的主要机制。

| Abstract: | This paper discusses the mechanisms of exciton thermal conductivity in the minerals of the mantle by using the Bose quantum statistical method, and the expression of the exciton thermal conductivity Kex is obtained. It also points out that the activation energy A has an important effect on the rate of change in exciton conductivity at high pressure and high temperature. The results indicate that exciton thermal conductivity may occur in the lower mantle, but it would not be a major mechanism of heat transfer. |
