| 摘 要： | 本文首先对单组分或组成不变的多组分系统给出磁场下的热力学系统的基本方程,导出熵为温度和磁场强度的函数S(T,H)的微分方程TdS=C_H_HT+μVT((aM)/(aT))_H dH并进一步证明顺磁性物质等温可逆放热,即Q<0,会导致系统磁场增高.根据宏观热力学理论这一结论,则磁铁矿的存在会导致地区气候温和宜人.

| Abstract: | The present work gives the thermodynamic equations for magnetic system under magnetic field and derives the differential equation of function S (T, H) as
From which it is proved that if the system is exothermic, i.e. , then its magnetic field will be increased. Then, the magnetite or paramagnetic salt will promote the climate warmly. |
