0.5%Pt-K/γ-Al2O3 catalysts for the synthesis of o-phenylphenol(OPP) from o-cyclohexenyl-cyclohexanone (dimer) dehydrogenation were prepared by means of a two s
深部隐伏酸性岩体形成（或侵入）产生的含矿气水热液沿断裂向上运移，在特定地质条件下反复充填交代成矿。地下水渗透或环流则从围岩或先期形成的矿床中溶解出矿质，在有利条件下沉积
测区引起磁异常的有磁铁矿（化）体和玄武岩，二者之间的磁性差异很大，为磁法勘探寻找磁铁矿奠定物性基础。通过磁法勘探的野外作业和室内数据整理分析，并经异常推断解释圈出矿体5个，
