ThermoML-An XML-Based Approach for Storage and Exchange of Experimental and Critically Evaluated Thermophysical and Thermochemical Property Data.2.Uncertainties

摘要

ThermoML is an XML-based approach for storage and exchange of experimental and critically evaluated thermophysical and thermochemical property data.Extensions to the ThermoML schema for the expression of uncertainties are described.Basic principles,scope,and description of all new structural elements are discussed.Representation of supper and lower limits for property values is also addressed.ThermoML covers essentially all experimentally determined thermodynamic and transport property data (more than 120 properties) for pure compounds,multicomponent mixtures,and chemicla reactions (including change-of-state and edquilibrium).Present.of polyimers adn radicals and some properties of ionic systems are not representd at present The present role of ThermoML in global data submission and sissemination is discussed with particular embhasis on cooperation between major journals in the field and the Thermodynamics Research Center (TRC) at te National Institute of Standards adn Technology.The text of several data files illustration the expression of sucertainties in ThermoML format for pure compounds,mixtures,and chemical reactions are provided as Supporting Information,as well as the complete updated ThermoML schema text.
