基于准经典近似研究强磁场中高温费米气体的统计性质,给出系统的统计特征量的解析式,分析磁场和温度对统计性质的影响.结果显示,与低温情况比较,高温下的统计特征量不再振荡,与自由费米气体比较,磁场总是降低系统的总能,增加系统的化学势、热容量、熵、压强和稳定性；而且温度越高,磁场对总能及热容量的影响越弱,对化学势的影响越大.

With quasi-classicsl approximations,statistic properties of Fermi gas in a strong magnetic field at high temperatures are studied.Analytical statistic characteristic quantities are given,and effects of magnetic field as well as temperature on statistic properties of the system are analyzed.Compared with a system in low temperatures,statistic characteristic quantities of Fermi gas in a strong magnetic field at high temperatures do not oscillate.The magnetic field decreases total energy of the system,and increases the chemical potential,heat capacity,entropy,pressure and stability of the system.The higher the temperature is,the weaker effects of magnetic field on total energy and heat capacity and the stronger effects on chemical potential are.
