摘　　要：物理化学在化学化工类、材料类、环境类、能源类等专业人才培养中都具有重要的作用和地位。“标准态”一词是物理化学中多次出现,正确理解各种“标准”的含义是掌握和使用很多重要的理论、公式、概念的基础。本文根据IUPAC的规定,将本科物理化学课程中的焓、熵、吉布斯自由能等热力学状态函数的“标准态”进行了整理、归纳和剖析,对物理化学教学和相关研究人员深入、准确地理解这一概念及相关理论有所帮助。Physical Chemistry plays an important role and status in the training of professional talents in Chemistry and Chemical Engineering,Materials,Environment and Energy.The term"standard"appears many times in Physical Chemistry.Correctly understanding the meaning of various"standards"is the basis for mastering and using many important theories,formulasand concepts.All the“standards”involved in thermodynamic state functions,including enthalpy,entropyand Gibbs free energy inundergraduate Physical Chemistry course was systematically organized,summarized and analyzed according to IUPAC stipulations.It was helpful to deeply and accurately understand this concept and related theories.
