摘　　要：A new representation of the Maxwell relation for phase transformation is given, which is expressed in simpler form and has more direct physical meaning than the original Maxwell relation. It is shown that the physical conjecture for the so-called "lock-up" condition suggested by Jensen (1999) is correct, but the equation for the "lock-up" condition suggested by Jensen (1999) is not. Numerical examples also demonstrate that the application of the new representation of Maxwell relation gives exactly the same solutions as the ones with application of the original Maxwell relation and, however, application of the "lock-up" condition gives no real solutions.A new representation of the Maxwell relation for phase transformation is given, which is expressed in simpler form and has more direct physical meaning than the original Maxwell relation.
