Results showed a high-purity and a good-integrity DNA can be obtained from the preserved fresh leaves of Camellia azalea, using the methods of modified CTAB and SDS subarea. The DNA extracting quality from the leaves preserved with silica gel by the methods of modified CTAB and SDS subarea is high, which is the same as from the leaves preserved at the -200C and liquid nitrogen, So these preserving methods are suitable for the fresh leaves of Camellia azalea, including for it from distant place.

TEM shows that drying by direct heating might result in hard aggregation of the tourmaline powder, while hard aggregation might be avoided by azeotropic distillation. Raman spectroscopy reveals that there are O_H and C_H on the surfaces of the tourmaline powder obtained by azeotropic distillation, which indicates that butoxy is chemically adsorbed on the surfaces of tourmaline particles, but not adsorbed on those formed by direct drying. X_ray powder diffraction shows that the intensity of diffraction peaks decreases after grinding. There is no damage to the tourmaline crystal lattice in the process of direct heating, azeotropic distillation, or ultrafine grinding.
透射电镜分析结果表明,直接加热脱去水或正丁醇会使电气石超细颗粒发生硬团聚,而共沸蒸馏法则可有效防止硬团聚的产生;拉曼光谱结果表明,共沸蒸馏法制备的电气石粉末表面存在O—H和C—H键,说明正丁醇在颗粒表面为化学吸附,而直接干燥法得到的电气石粉末表面则没有;X射线粉晶衍射结果表明,研磨过程降低了粉末衍射峰的强度,但直接加热干燥和共沸蒸馏干燥均未破坏电气石的晶格结构。
