中文摘要：

单组分单相不发生化学变化的系统,自由度为2,如要考虑磁场,则自由度为3。本文基于温度、压力和磁场三个独立强度性质,合理地给出磁场下平衡过程的热力学的基本方程组。本文计算了在磁场为1万高斯和温度在253,273,293和313K时核磁子^17O,^33S和^77Se的磁极化M和磁性热力学函数。

英文摘要：

For single component and single phase systems, the freedom is 2, and will be 3 if the magnetic field is involved. The present work gives the fundamental equations of thermodynamics under the con-sideration of temperature, pressure and magnetic field. The present work is to calculate the magnetic thermodynamically functions and magnetization of magnetic nucleus of ^17O, ^33S and ^77Se.
