analyzing crystal
2.Abstract: While we were analyzing the proposed theory about the crystal growth,we doubted that the interface phase existed in the process of crystal growth.With this,we had looked for a lot of references connected and analyzed them.We find that the interface-phase does exist in the process of crystal growth and takes a critic role.Therefore,we divide the interface-phase into three co-relative parts:interface layer,adsorptive layer and transitive layer.Base on the above ideal,we demonstrate the role of interface layer,adsorptive layer and transitive layer in the process of crystal growth respectively.Furthermore,we proposal the interface-phase model about the crystal growth.
4.The manufacturing process for VDC/VC polyvinylidene chloride film was simulated step by step to analyze the effect of processing parameters, including temperature, strain and time, on the crystallization. Some analyzing techniques like X ray diffraction and DSC were applied to observing the crystal structure of samples.
6.For analyzing the causes on degeneration of the black soil in corn belt,the authors made a pilot study of the clay mineral compositions and their distributions in the black soil of the corn belt of central Jilin,by applying the X-ray diffraction method. The results show that the clay mineral compositions are characterized by montmorillonite and illite with single crystal structure type 2∶1,the contents of the two clay minerals account for 90% in total.
