摘要:
采用非平衡量子统计方法讨论了地幔矿物声子热传导的3种不同情况,得到了较为普遍的结 果,结果表明在下地幔声子热传导将是主要机制。
Abstract:
According to the new literatures of the physical properties of minerals in the mantle under high temperature and high pressure, the processes of stimulation, transfer and absorption of phonons of minerals in the mantle were investigated by using nonequilibrium quantum statistics. It had been found that the mechanism of the thermal conductivity of phonons of minerals in the mantle could be divided into three kinds. The results show that: In the transit zone and submantle, the phonon thermal conductivity is the main mechanism of minerals in the mantle because that pressural effects surpassing temperatural effect causes phonon thermal conductivity increasing with the depth;In the mantle, if Boses condensing phenonmenon under nonlinearity and nonequi-librium state exists, a great quantity of optical braching phonons will enter the same vibration energy level and the optical braching phonons will play a leading role in the phonon thermal conductivity.
