| 摘 要： | The cold-melting mechanism and the cold-dissolving-melting mechanism were further studied by TG/DTA and in situ micro-photographs techniques with the mixture of dimethylglyoxime and Ni(Ac)2·4H2O, and the mixture of dimethylglyoxime and anhydrous Ni(Ac)2 as the modeled reactive examples. The endothermic peaks on the DTA curves at about 38 ℃ revealed the formation process of the cold-melting layer and cold-dissolving-melting layer on the surface of reactant particles. Further, the cold-melting state and the cold-dissolving-melting state were observed by the micrographs. These results provided the direct evidences for the theories of cold-melting mechanism and the cold-dissolving-melting mechanism.
