【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。更多还原

【Abstract】 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%.更多还原
