摘要翻译：
通过与Monte Carlo模拟的比较，证明了自洽Ornstein-Zernike方程(SCOZA)和分层参考理论(HRT)两种液相理论能够很好地预测硬核汤川流体(HCY)在长程作用下的液汽共存。在模拟中，利用Ewald和和超球面边界条件处理了势的长范围。此外，我们提出了一个解析的优化平均场理论，它在无限长程相互作用的极限内是精确的。这项工作扩展了Caccamo等人[Phys.Rev.E,60,5533(1999)]关于短程相互作用的先前研究。

英文摘要：
Two liquid state theories, the self-consistent Ornstein-Zernike equation (SCOZA) and the hierarchical reference theory (HRT) are shown, by comparison with Monte Carlo simulations, to perform extremely well in predicting the liquid-vapour coexistence of the hard core Yukawa (HCY) fluid when the interaction is long range. The long range of the potential is treated in the simulations using both an Ewald sum and hyperspherical boundary conditions. In addition, we present an analytical optimised mean field theory which is exact in the limit of an infinitely long range interaction. The work extends a previous one by Caccamo et al [Phys. Rev. E,60, 5533 (1999)] for short range interactions.
