摘要：

In the present paper a model of thermal contact in transient state using the notion of "thermal quadripoles" is presented. This model takes into account two particular aspects of the transient state: the establishment of the heat flow lines and the heat capacities of both contact spots and interstitial fluid. Two experiments in steady periodical state are shown: one deals with real contacts, whereas the other concerns a macro-contact. The latter shows good qualitative agreement with the proposed model. In the real contact case, satisfactory agreement is obtained for the 0-0.02 Hz frequency range; for the 0.02-0.1 Hz range, differences are observed and stay yet unexplained.
