摘　　要：用热力学基本定律和(火用)的基本概念讨论了(火用)的普遍化表达式的应用,证明了热(火用)、压(火用)和化学(火用)的计算都必然与熵变相联系,“如果过程中没有热(火用)的传递和转换,过程就没有熵增”的说法是不能成立的。The generalized expressions of Exergy and its applications are discussed based on Thermodynamic Laws and exergy's definition. The heat exergy, pressure exergy, and chemical exergy are consequentially related with the variation of system entropy. It is indicated that the parlance of 'If there is no transferring or transforming of heat, there will be no increase of entropy in the process' is incorrect.
