【摘要】 氦-3作为氦-4的同位素，其特殊的物理性质和化学性质越来越受到人们的关注，它在低温工程，基础物理学和空间技术等方面应用的重要性也得到了充分的认识。这些应用都要以氦-3的热力学和传输性质作为基础。然而，目前关于氦-3的试验数据十分稀少，有关于氦-3的热力学性质和传输性质的计算方法也没有统一的标准。本文主要研究了氦-3的焓、熵热力学性质计算和传输性质的计算，开展了以下几方面的工作： 1．收集了大量关于氦-3的文献，整理了其中的传输性质数据，并将其转换为可以查找的电子数据库，以便于对氦-3的性质进一步的研究。 2．作为尝试采用对改进的量子对应态原理，对氦-3焓和熵的热力学性质进行了计算和预测。 3．分别采用改进量子对应态原理和碰撞积分模型对氦-3的热导率进行了计算和比较。结果表明，利用改进量子对应态原理的计算结果在较高的温区具有较好的精度。 4．利用改进量子对应态原理对氦-3的粘度性质进行了预测，取得了满意的结果。更多还原

【Abstract】 As the isotope of helium-4, helium-3 is more and more attracted by scientists because of its special physical and chemical properties. And now, helium-3 is having many applications in the fields of cryogenic engineering, fundamental physics and space technology, etc. All these applications depend on the thermodynamic properties and transport properties. However, there is little experimental data of helium-3 and no uniform method to calculate its properties. This paper deals with the enthalpy entropy and transport properties of helium-3. The main research contents are as follows:1. Sufficient reference and different types of data have been collected into a searchable database, which is very necessary and convenient for the further research on helium-3.2. Calculation and prediction of the enthalpy and entropy of helium-3 are attempted by using the modified quantum version principle of corresponding states.3. Calculations of the thermal conductivities of helium-3 using the modified quantum version principle of corresponding states and the collision integrals model. It shows that there is a good result in a relative high temperature region using the modified quantum version principle of corresponding states.4. Prediction of the viscosity of helium-3 are presented by using the modified quantum version principle of corresponding states and some reasonable result have been obtained.更多还原
