摘要
从最大熵原理出发,在经典和量子2种情况下,研究了顺磁物质的磁化规律,得到了顺磁物质磁化强度的表达式,在高温弱磁情况下,磁化强度与外磁场成正比,与温度成反比,得到的结论与统计物理中的系综理论或最该然分布结论一致。该原理不仅适用于平衡态问题,而且也适用于非平衡定态问题。
The magnetization law of paramagnetic substance was studied under classical and quantum condition based on maximum entropy principle. The results showed that magnetization intensity was proportional to magnetic intensity and inversely proportional to temperature under high temperature and low magnetic intensity, which agreed with to the results obtained from ensemble theory or most probability distribution theory. Maximum entropy principle applied not only to the problem of equilibrium state, but also to the problem of non-equilibrium stationary state.
