摘要：

Entransy is a function recently introduced in thermodynamics. This function is analyzed critically in relation to the classical thermodynamic approach in order to understand its physical fundamentals. The crucial problem is that thermodynamic analysis shows that entransy does not contain any new information in comparison with a classical thermodynamic analysis of systems. Furthermore, entransy dissipation analysis is a duplicate of entropy generation analysis.
