The entropy or number of states of system or subsystem are closely related to interaction of particles and energy level distribution, therefore, to study the temperature dependence of the specific heat may supply some important and useful microscopic information which may play an important role in understanding electronic structure, density of state, phonon spectrum etc. the specific heat measurements at low temperatures also play important roles in the finding of the third law of thermodynamics, the quantum theory of solid and bcs theory for superconducting etc. moreover, specific heat measurements help us to understand the different kinds of phase transitions ( such as : structural phase transition, magnetic phase transition, superconducting phase transition etc. ) and the scaling behavior near the critical point

By applying the theory and method of geological anomaly, it is focused on the analysis of the characters of major geological anomalies and their effect of mineralization in daye - jiurui region. the analysis result shows that the basement fault anomalies control a few major large hidden batholiths and their associated orefields ; that the anomalies of cover structure confine most cu - au deposits and fe - cu deposits within their scope ; that the geochemical anomalies and lithofacies - paleogeographical anomalies are major geological factors leading to trataboundness of some cu - au deposits ; that the anomalies of rock operties provide the favorable chemical and physical conditions for the ore - forming process, including the seepage, circulation, convergence and deposit of ore - bearing hydrothermal solution ; that the anomalous ctive stage of mesozoic magmatite is almost consistent with the major mineralization epoch of the fe, cu deposits, and the structure of multi - levels, and the zoning in magmatic system determine the spatial distribution of the mineralization system. then, based on the above analysis, a comprehensive variate, geological combination entropy, is brought forward for reflecting the complex degree of the combination of geological ore - controlling factors. after circumscribing the anomalies of geological combination entropy, the relations between the anomalies and ore deposits are determined
