Using the rotational isomericstate theory, the mean square radius of gyration < S 2> and its temperature coefficient for the polymer chain with large side groups are derived.
However, the selected area's electron diffraction shows that it has both cubic and hexagonal phase structures corresponding to different shapes. This is attributed to the isomericstate of ZnS.
样品选区电子衍射表明反应产物是立方相和六方相结构，认为这是硫化锌的同质异构现象。

QCD isomeric compounds and a tetra-quark state with the square-like color structure based on a color string model and the similarity between string and chemical bond are proposed and studied.
