Therefore, butoxy in n_butanol can be adsorbed chemically on the surfaces of the tourmaline particles in the process of azeotropic distillation, which can effectively prevent the formation of liquid_bridge between the particles of tourmaline and avoid the hard aggregation in the drying process.

正丁醇中的丁氧基在共沸蒸馏过程中在电气石颗粒表面可取代羟基，产生化学吸附，能有效防止液桥的产生，阻止干燥过程中超细粉末的硬团聚。

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。

Ferrocenecarboxylic-ssdeoxyribonucleic acid probe was made by chemically bounding FCA to terminal 5'-amino of oligonucleotide in the presence of a water-soluble carbodiimide. The hybridization reaction was conducted by immersing the immobilized-ssDNA electrode in FCA-ssDNA probe solution.

在偶联活化剂碳二亚胺的存在下，通过羧基二茂铁上的羧基与DNA分子上的氨基共价键合，将FCA标记在氨基修饰的寡聚核苷酸片段上，制备成FCA-ssDNA探针。

objective effects of plant tannins,chebulinic acid and tellimagrandin i on chemically induced hemoglobin synthesis in k562 cells were investigated.methods the hemoglobin synthesis situation was assayed with benzidine staining.erythroid antigens glycophorin a expression on the surface of k562 cells was labeled by direct immunofluorescence using fluorescein isothiocyanate-conjugated anti-gpa antibodies.then flow cytometric analysis was performed to detect gpa expression levels on surface of the cells.results both chebulinic acid and tellimagrandin i could inhibit the hemoglobin synthesis of butyric acid and hemin-treated k562 cells in a concentration-dependant manner.however,the ba-induced k562 cells were more sensitive to two tannins than heroin-induced cells.conclusion chebulinic acid and tellimagrandin i have inhibitory effect on the erythroid differentiation.

目的 研究可水解单宁诃子酸和特里马素i对氯化高铁血红素和丁酸钠诱导k562细胞红系分化的影响。方法四甲基偶氮噻唑蓝法分析诃子酸和特里马素i对k562细胞生长的影响，联苯胺染色法检测血红蛋白合成情况，应用免疫荧光和流式细胞术检测血型糖蛋白a在细胞表面的表达。结果诃子酸和特里马素i在0.04～0.09？mmol／l浓度下均可显著抑制k562细胞的生长增殖。2种单宁化合物(0.002～0.01？mmol／l)可显著抑制丁酸钠诱导的k562细胞血红蛋白合成，2种单宁化合物(0.01～0.05？mmol／l)还可显著抑制氯化高铁血红素诱导的血红蛋白合成，特里马素i(0.01？mmol／l)还抑制丁酸钠诱导的gpa在细胞表面表达。结论诃子酸和特里马素i对红系分化有抑制作用。
