【摘要】 基于最新的氦-3饱和曲线特征方程,熔化曲线特征方程以及德拜模型氦-3状态方程绘制了氦-3在0．2 K-300 K,0．0001MPa-30MPa范围内的p-h图和T-s图。与先前基于实验数据及数值计算方法绘制的0．2 K-20 K温区氦-3的p-h图和T-s图相比,该图不仅适用的温区得到了大大的拓展,同时也使得计算有了热力学理论基础,可靠性更高。更多还原

【Abstract】 Based on the saturated vapor-pressure equation, saturated density equation, melting-pressure equation, melting-density equation and state equation of helium-3, the p-h and T-s graphs of helium-3 have been plotted in the range of temperature form 0.2 K to 300 K and pressure from 0.0001MPa to 30MPa. Compared with the p-h and T-s graphs (0.2 K to 20 K) which have been plotted based on the experimental data and numerical calculation previously, the new graphs possess a larger scope of application and the calculation has a thermodynamic theoretical support which makes the new graphs more reliable.更多还原
