Referring to ISO 19115 and DIF standards, this paper presents a metadata standard draft of marine information based on XML, which can be implemented to describe, organize, store and manage the marine information. The metadata standard is represented in XML, which is easy to apply. And gives the details of main marine metadata XML elements. On this basis, the marine metadata directory service system...
The polyoxometalate (CPFX·HCl)3H3PW12O40·8H2O was prepared and characterized by elemental analysis, IR spectra and TG-DTA-DTG. The thermal decomposition mechanism and non-isothermal kinetic parameters of the polyoxometalate were obtained from the analysis of TG-DTG data using the Achar equation, Coats-Redfern equation (CR), Madhusudanan-Krishnan-Ninan equation (MKN) and Horowitz-Metzger equation (HM)...
