摘要：
用最低阶约束变分法研究了有限温度下自旋极化液体$^3\mathrm{He}$的热力学性质。对于该系统，计算了不同密度、温度和极化率下的自由能、熵和压强。给出了比热、饱和密度和不可压缩性与温度和极化的关系。
英文摘要：
We have investigated some of the thermodynamic properties of spin polarized liquid $^3\mathrm{He}$ at finite temperature using the lowest order constrained variational method. For this system, the free energy, entropy and pressure are calculated for different values of the density, temperature and polarization. We have also presented the dependence of specific heat, saturation density and incompressibility on the temperature and polarization.
