流體相平衡發(fā)表了有關(guān)流體、固體和界面平衡和傳輸特性的實(shí)驗(yàn)、理論和應(yīng)用研究的高質(zhì)量論文。感興趣的主題包括物理/相和化學(xué)平衡、平衡和非平衡熱物理性質(zhì)、基本熱力學(xué)關(guān)系和穩(wěn)定性。該期刊的核心系統(tǒng)包括純物質(zhì)和有機(jī)和無機(jī)材料的混合物，包括聚合物、生物化學(xué)物質(zhì)和表面活性劑，它們對組成和純度有充分的表征，以使結(jié)果得以重現(xiàn)。只有當(dāng)熱力學(xué)研究被包括在內(nèi)時，合金才有意義，純材料研究將不被考慮。在所有情況下，作者應(yīng)提供結(jié)果的物理或化學(xué)解釋。實(shí)驗(yàn)研究可以包括在所有溫度、壓力和成分條件下的測量，包括臨界和超臨界。測量應(yīng)與系統(tǒng)和基本或應(yīng)用感興趣的條件相關(guān)聯(lián)，并且可能不僅是常規(guī)數(shù)據(jù)的集合，例如物理性質(zhì)或在接近環(huán)境的有限壓力和溫度下的溶解度測量，或者表面活性劑研究嚴(yán)格關(guān)注膠束化或膠束結(jié)構(gòu)。報告共同數(shù)據(jù)的論文必須附有新的物理見解和/或當(dāng)代或新的理論或技術(shù)。所有數(shù)據(jù)報告和分析將由NIST檢查是否符合http://trc.nist.gov/fpe-support.html上發(fā)布的要求。理論和計算研究可以包括狀態(tài)方程、關(guān)聯(lián)或預(yù)測模型、分子動力學(xué)和蒙特卡羅模擬、統(tǒng)計熱力學(xué)、量子化學(xué)以及其他應(yīng)用數(shù)學(xué)和計算方法。報告新理論和模型的研究預(yù)計將顯示預(yù)測能力和準(zhǔn)確性與適用數(shù)據(jù)和當(dāng)代現(xiàn)有模型的充分比較。只有在提供了方法的全部細(xì)節(jié)，并將精度與現(xiàn)有的物理模型進(jìn)行了比較，或沒有可用的熱力學(xué)模型時，才會考慮對人工神經(jīng)網(wǎng)絡(luò)、機(jī)器學(xué)習(xí)和類似方法的貢獻(xiàn)。所有報告的計算研究必須能被其他人完全復(fù)制。因此，所有算法和方法都應(yīng)詳細(xì)描述，模型、力場和電子結(jié)構(gòu)方法的所有參數(shù)應(yīng)在手稿或支持信息中明確給出。該雜志發(fā)表了完整的研究論文和簡短的交流，以描述快速出版是必不可少的新思想。鼓勵進(jìn)行評論，并應(yīng)與總編輯協(xié)商準(zhǔn)備。期刊不會發(fā)表在其他期刊上部分或全部出現(xiàn)的、剽竊其他作品或引用不完整的文章；將使用http://www.itheticate.com/products/crosscheck上的軟件進(jìn)行驗(yàn)證。文本必須是英文的，并應(yīng)清晰，結(jié)構(gòu)良好的風(fēng)格，沒有語法和拼寫錯誤。

Fluid Phase Equilibria publishes high-quality papers dealing with experimental, theoretical, and applied research related to equilibrium and transport properties of fluids, solids, and interfaces. Subjects of interest include physical/phase and chemical equilibria; equilibrium and nonequilibrium thermophysical properties; fundamental thermodynamic relations; and stability. The systems central to the journal include pure substances and mixtures of organic and inorganic materials, including polymers, biochemicals, and surfactants with sufficient characterization of composition and purity for the results to be reproduced. Alloys are of interest only when thermodynamic studies are included, purely material studies will not be considered. In all cases, authors are expected to provide physical or chemical interpretations of the results.Experimental research can include measurements under all conditions of temperature, pressure, and composition, including critical and supercritical. Measurements are to be associated with systems and conditions of fundamental or applied interest, and may not be only a collection of routine data, such as physical property or solubility measurements at limited pressures and temperatures close to ambient, or surfactant studies focussed strictly on micellisation or micelle structure. Papers reporting common data must be accompanied by new physical insights and/or contemporary or new theory or techniques. All data reports and analyses will be examined by NIST for consistency with the requirements posted at http://trc.nist.gov/FPE-Support.htmlTheoretical and computational studies can include equations of state; correlations or predictive models; molecular dynamics and Monte Carlo simulations; statistical thermodynamics; quantum chemistry; and other applied mathematical and computational approaches. Research reporting new theories and models are expected to show adequate comparisons of predictive ability and accuracy with both applicable data and contemporary existing models. Contributions on artificial neural networks, machine learning, and similar approaches will only be considered when full details of the methodology are provided and comparisons of accuracy are made with existing physically-based models, or if no thermodynamic models are available. All reported computational studies must be fully reproducible by others. As such all algorithms and methods should be described in sufficient detail, all parameters for models, force fields, and electronic structure methods should be given explicitly in the manuscript or supporting information.The journal publishes full research papers and also short communications to describe emerging ideas for which rapid publication is essential. Critical reviews are encouraged and should be prepared in consultation with the Editor-in-Chief. The journal will not publish articles that have appeared partially, or completely, in other journals, that plagiarize other works, or that are incompletely referenced; verification will be made using the software at http://www.ithenticate.com/products/crosscheck. The text must be in English and should be clear, in a well-structured style, and be free of grammatical and spelling errors.
