结晶化学

Elemental and isotopic data suggest that the chemical variations of the HT and LT lavas can not be explained by crystallization from a common parental magma.

元素和同位素数据表明，HT和LT熔岩的化学变异不是由一个共同母岩浆的结晶分异作用所产生。

This paper has investigated the microstructures, quartz fabrics, and mineral chemistry of mylonites from the ductile shear zone of the granite-greenstone belt in Seerteng area, Inner Mongolia. Synthetic analyses reveal that the mylonites underwent four evolutionary processes of deformation and metamorphism, such as lower-amphibolite facies regional metamorphism, retrograde epidote-amphibolite facies metamorphism and deformation, progressive recrystallization and retrograde greenschist facies metamorphism and deformation.

通过相关数据的统计分析，找出了化学成分、结晶器使用次数、保护渣碱度、钢板厚度、装炉方式、冷却强度等对钢板显裂的影响规律；分析显裂产生的原因是，Cu原子、硅酸盐类夹杂物富集在奥氏体晶界，降低晶界强度，诱发显裂。

The α-BaB〓O〓 crystal is colorless, transparent and without cracking. The cracking problem has been overcome by a special growth procedure. The dislocation density, crystallization morphology and growth habit of α-BaB〓O〓 crystal have been systematically studied by chemical etching method, X-ray laue orientation of synchrotron radiation, double-crystal diffraction topography.
