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

  5. Abstract : polyphenylacetylenes were synthesized by rn ( nbd ) cl 2 and wcl6 / ph4sn catalyst systems in n2 at room temperature. polymers with high yield and high molecular weight were obtained. their structures were characterized by uv, ir, nmr and gpc, respectively. the fluorescence of the polymer solution with different concentration was investigated using variable excitation wavelength from uv to visible region. the relation between fluorescence and polymer structure was studied. the results showed that the molecular chain structure has great influence on fluorescence of the polymers. the emitting peak wavelength of fluorescence for the polymer of high stereoregularity is independent of solution concentration and excitation wavelength. the emitting peak wavelength of fluorescence for the polymer with disordered molecular chain arrangement varies with changing the solution concentration and excitation wavelength, and different emission sites in molecular chains and low emitting yield are shown. the measurement and analysis of fluorescence spectroscopy of polyphenylacetylenes may provide some useful information to judge the molecular chain arrangement in some conjugated polymers
