中文摘要：
基于最新的德拜模型氦-3状态方程、氦-3饱和曲线特征方程和熔化曲线特征方程编写了氦-3热物性计算程序.在大量热物性的计算数据的基础上绘制了氦-3在0.2 K～300 K,0.000 1MPa～30 MPa范围内的p-h图和T-s图.与先前基于实验数据绘制的0.2 K～20 K温区氦-3的p-h图和T-s图相比,该图的绘制是建立在热力学理论计算的基础之上,适用温区得到了拓展,随机误差一般在2%以内.
英文摘要：
Based on the Debye state equation and the phase equilibrium equations of helium-3, a computer program for calculating the thermodynamic properties of helium-3 has been developed. Based on a series of calculations, the p-h and T-s graphs of helium-3 have been plotted in the range of temperature from 0.2 K to 300 K and pressure from 0. 000 1MPa to 30 MPa. Compared with the p-h and T-s graphs （0.2 K to 20 K） plotted based on the experimental data before, the new graphs are based on the thermodynamic theoretical calculation and provide a broader temperature scope of application. The overall random errors of these two graphs are within 2%.
