二元溴化物系中间化合物的形成规律

在由原子键参数(z/r)_M、X_M'、I_M及I_M'张成的多维空间中,能形成和不能形成MBr-M'Br₂系中间化合物的样本点分布在不同的区域.利用超多面体模型描述了能形成MBr-M'Br₂系中间化合物的样本点在多维空间中分布区域的边界.在此基础上预报并验证了RbBr-CaBr₂和CsBr-CaBr₂这两个熔盐体系可形成中间化合物.

The Rule Governing the Formation of Binary Bromide System

A new pattern recognition method called hyper-polyhedron model has been proposed for investigating the rules governing the formation of binary complex bromide systems by using the atomic parameters (z/r)M、XM′、IM、IM′. It has been found that the representative points of binary complex compound-forming systems and those of the systems without binary complex compound are distributed in different regions in the multidimensional space spanned by the atomic parameters. By using hyper-polyhedron method, a hyper-polyhedron model can be obtained to describe the boundaries of the zone where all the binary complex compound-forming samples are distributed. It is proved by means of the hyper-polyhedron model that RbBrCaBr2 and CsBrCaBr2 are binary complex compound-forming systems.
