查询词典 characterization

A new thought line of reservoir characterization is put forward based on the combination of the high resolution sequence stratigraphy,the architectural element and flow unit analysis method.It integrates the static geological body with the dynamic developing process,the reservoir heterogenesis with oil and water distribution from macro scale to micro scale.

To isolate forebrain and hindbrain of human fetuses about 9 weeks and 12 weeks from spontaneous abortion. Neural stem cells were cultured in special culture medium and were compared with growth characterization.The differentiation from these neural stem cells was investigated in both a fetal bovine serum-containing and a non-supplemented,serum-free basal medium.

材料与方法：利用神经干细胞的条件培养基，对从9周和12周胚龄的自然流产胎儿分离的前脑、后脑进行神经干细胞培养，比较其生长特性，并分别观察在无生长因子的基础培养基以及含有胎牛血清的培养基中神经干细胞的分化情况。

成鱼组织中，Caghira在卵巢和脑中均有表达，但脑中表达量较弱，说明该基因在维持卵巢和脑组织作用中起一定作用。

The result of WISH showed that the trascription of hira gene distributed widely in the early stages of embryos development and centralized to head, heart and the end of tail. Hira gene might affect the development of brain and heart. The expression characterization of colored crucian carp Cahira gene in different tissues and different stages of embryogenesis were also investigated by RT-PCR.

胚胎原位杂交显示，Hira基因的转录本在银鲫胚胎早期广泛分布，而在胚胎后期主要集中于头部、心脏及尾芽尖部，说明也对其脑部和心脏的发育有影响。

The orange osmanthus skin-traditional Chinese medicine being taken as raw material, the active ingredient-phenol was extracted with the method of steam distillation and then the derivative of paeonol-aminoethanol and 2,4-dinitrophenyl hydrazone was synthesized. The structural characterization of the derivatives carried out was identified and the test in the anti-bacterial role of three kinds of gram-negative and positive bacteria was done with the method of agar diffusion.

方法］以丹皮为原料，用水蒸气蒸馏法从中药丹皮中提取活性成分丹皮酚，进而合成丹皮酚缩乙醇胺和2，4-二硝基苯腙衍生物，对衍生物进行了结构表征，并采用琼脂扩散法，对3种革兰氏阴性菌、阳性菌进行了抑菌性试验。

On the NiO/SiO〓 catalyst prepared by IM, the main hydrogenation product of MA was SA, the activity and selectivity were almost no relation with the nickel content and nickel species 3. Summarizing the characterization and activity evaluation of the catalysts, we concluded: On nickel based catalyst, when NiO was crystallite, and the Ni〓 that was prepared by reducing, hydrogenation of the MA could lead to SA but not to γ-BL; when NiO was cluster and had a properly interaction with the support, the Ni〓 prepared by reducing, could hydrogenate MA to SA then to γ-BL. When NiO cluster and crystallite were both existed on the catalyst, the hydrogenation products were mixture of SA and γ-BL, and the amounts of SA and γ-BL were related with the ratio of cluster and crystallite.

综合催化剂的表征和活性评价得出：当镍基催化剂上氧化镍以结晶态存在，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到丁二酸酐，丁二酸酐难以进一步加氢为γ-丁内酯；当镍基催化剂上氧化镍以簇团形式存在，与载体之间有适当的相互作用时，经氢还原后的零价镍可使顺丁烯二酸酐加氢得到的丁二酸酐进一步加氢为γ-丁内酯；若催化剂上氧化镍既有结晶态又有簇团形式时，随二者含量比例不同而得到丁二酸酐和γ-丁内酯的混合物。
