Investigates thermodynamically the Pb-oxychlorides formed during urban refuse incineration/melting by way of high-temperature XRD and activity determination of such solid oxychlorides,including the binary phase diagram of PbO-PbCl_2,the relative chemical potential of PbO and standard free energy of formation or Gibbs free energy of activation of intermediate compounds.
以城市垃圾焚烧灰渣熔融处理中铅氯氧化物体系为研究对象,根据高温X射线衍射及固相氯氧化物的活度测定结果,对PbO-PbCl2系组成相图、PbO相对化学位及固相中间化合物的标准生成自由能等Pb-O-Cl系的热力学性质进行了研究,从而为熔融处理中铅氯氧化物的生成和沉聚反应的热力学解析提供理论依据。
Derivation of standard free energy of formation for binary compounds to be obeyed a quasi-parabola regulation and extension to ternary systems to be obeyed a quasi-paraboloid regulation were carried out on the basis of thermodynamic principle.
本文从热力学原理出发，推导出：二元系中化合物的标准生成自由能符合似抛物线规则；推广到三元系则应符合似抛物面规则。
