主　　题：Wettability and Thermodynamic Adhesion of Liquid Metals on Solid Uranium Dioxide der 

摘      要：Using the experimental results given in literatures about the contact angle, θ and the work of adhesion, W, for nonreactive liquid metal / solid UO_2 systems, the validity and feasibility of the different existing models for calculating W in the metal /ox- ide systems are discussed. It can be shown that the models assuming that only metal atom-oxygen ion interactions existing at the interfaces are unable to explain the experimental results for W. More reasonable model should take into account both metal atom-oxygen ion and metal atom-oxide metal cation interactions, the proportion of the latter is balanced by the stoichiometry of the oxide. By applying the model recently set up by the authors for binary alloy / oxide systems, one can use the experimental and calculated values of θ and W for various metal / UO_2 systems to predict the influence of metallic additions on the contact angle and the work of adhesion of a given metal / UO_2 system.
