The duality of the Gibbs dividing surface is clearly shown and emphasized: the variation in curvature of any dividing surface consists of, (1) the variation as an intensive state variable—to be called "physical variation"—and (2) the variation in the choice of location of the dividing surface—to be called "non-physical variation." for it can be performed without changing any condition of the system. Upon these clearified fundamental concepts are established the strict fundamental equations for a system including curved interface. Comparison of our equations with Gibbs' equation reveals that Gibbs' equation are identical in form with ours, but he misunderstood the meaning of the curvature terms in his equations owing to the fact that he ignored the above-mentioned duality of the dividing surface. The conventional method of derivation of the Kelvin relation is criticized and proved erroneous in its strictress: the Kelvin relation results only when the surface tension is referred to the "surface of tension" which is defined as the dividing surface to give minimum value to surface tension. Thus most of the text books of thermodynamios should be rewritten at this point. The surface of tension as ill-defined by Gibbs and Tolman does not lead to the Kelvin relation. It is proved by a new method that the Kelvin relation results independently of the thermodynamical variation, i. e., it results as a necessary condition of mechanical equilibrium even if the system is not in equilibrium thermally or chemically.
