【摘要】 在广泛收集和整理文献数据的基础上 ,自行开发了氦 3热物性数据计算程序 ,它适用于温度 1K～ 1 0 0K ,压力 1 0MPa以内的使用范围。以压力、温度、比容 (或密度 )、焓、熵、内能中任意两个作为输入参量 ,可以计算其余热力参量、热导率以及动力粘度等输运性质。输入输出单位制种类齐全 ,可任意互换。在上述区间内 ,计算具有连续性 ,最大误差在 5‰以内。更多还原

【Abstract】 A self-built computer program for the properties of He-3 between the temperature 1K and 100 K,the pressure up to 10 MPa is introduced.Arbitrarily selecting two property parameters among pressure,temperature,specific volume(or density),entropy,enthalpy and internal energy as the input variables,the rest,the thermal conductivity and viscosity could be calculated.The comprehensive unit system of the input and output parameters,the continuity of calculating and the high accuracy with the maximum error within 5‰ characterized this program as a feasible one.更多还原
