查询词典 groups

Novel chitosan derivative with long alky groups as the hydrophobic moieties and carboxymethyl groups as the hydrophilic moieties was synthesized. The chemical structure of N-octyl-O, N-carboxymethyl chitosan was characterized via FTIR, 1H NMR and elemental analysis. The physical properties were analyzed with wide angle X-ray diffraction and differential scanning calorimetry.

以天然可生物降解的壳聚糖为原料，通过在壳聚糖6位羟基上引入羧甲基，在2位氨基上引入疏水烷基链，制得N-辛基－O，N-羧甲基壳聚糖两亲性衍生物，分别用FTIR、1H NMR和元素分析等技术对其结构进行表征，用广角X射线衍射和差示扫描量热法对具物理性质进行分析，并考察其在各种溶剂中的溶解性能及其对难溶性药物的增溶能力。

Particularly preferred as Rc and Rd groups are alkyl groups of from 2 to 8 carbon atoms.

最佳的Rc和Rd为含2～8个碳原子的烷基。

Finally, allelomimetic behavior is highly developed among most primate groups, where it has the principal function of providing warning against predators, though combined defensive behavior is also seen in groups of baboons.

最后，互访行为在灵长类动物群体中得到了进一步发展，其主要作用是为防范敌人提供警戒，尽管在狒狒群体中联合御敌的现象也是有的。问题点数：0、回复次数：1

Moreover, it was successfully linked with lactobionic acid through amine groups on the surface of particles, and used to recognize living liver cells successfully.(3) In order to simplify the proceeding of preparation of silica-coated qdots, a novel one-pot method using 3-mercaptopropyl-trimethoxysilane as a capping molecule was proposed for the first time. Furthermore, amine and phosphonate groups were also modified on the surface of silica-coated qdots simultaneously. This was the first time the synthesis and the surface modification of qdots were performed in the same system.

3在前一部分工作的基础上，进一步简化量子点的合成与包壳步骤，以MPS为稳定剂，制备了硅壳包被的CdTe量子点，并在硅壳外同步修饰氨基及磷酸基团，首次成功实现了量子点的合成与表面的功能化修饰在同一体系中进行，从而制得了水溶性的、表面带有氨基和磷酸基团的硅壳型CdTe量子点。

Then select some interested groups to explore and ANE will gather all the addresses and names from these groups.

然后选择一些有兴趣的团体探索和ane将聚集所有的地址和名称，从这些群体。

GROUP 2 showed that the time of MMC IIphase was longer than other groups (P. 01), while that of I phase^ III phase was normal; there were six patients without III phase, and three had antidromic conduction; GROUP 3 showed that the time of MMC I phase was longer than other groups (P. 01).while that of II phase ^ III phase was shorter; there were nine patients without III phase, and two had antidromic conduction.

FD肝郁气滞组表现为MMCⅡ相延长，Ⅰ相、Ⅲ相不延长；有6例无Ⅲ相出现，有3例出现逆向传导，Ⅲ相起始于十二指肠；脾胃虚弱组表现为Ⅰ相延长，Ⅱ相、Ⅲ相缩短；有9例无Ⅲ相出现，有2例出现逆向传导。

At the festival , Zhuang people get together in groups , either in fields or on hillsides , singing folk songs in antiphonal style among members within a group or among members in different groups .

的"歌圩节"，壮族人集中在田野或山坡上，分组对歌，或同一组的人轮唱。

Male patient was prevalent in aphasic groups, but mean age of both gender groups was no difference. The possible explanations may be adduced for our findings; one is related to the cerebrovascular changes of aging- The decrease of cerebral circulation is prominant and disseminated in increasing age. There may be changes in the cerebral blood flow associated with aging, predisposing different brain areas to stroke. The second is possible that changes in cognition, deterioration of memroy and comprehension disturbance may predispose the perception dysfunction of language or advanced language dysfunction like global aphasia in aging group.

在各类失语症中，Broca矢语症的平均年龄为54岁，明显的比全失性失语症的平均年龄64.6岁和经皮质层感觉性失语症的平均年龄61岁都小，显示Broca失语症较易发生於年龄较轻者，而年龄较大者发生全失性失语症和经皮层感觉性失语症的机会较多，至於男女两组失语症病人在平均年龄上并无明显差异，但失语症的发生率男性比女性多，且性别上的差异也与失语症的型式有明显相关。

With increasing DMFcontent in mixed solvents, the dipolar attracting interactions betweenglycine molecules increase; the attracting interactions arising fromhydroxyl groups between L-serine molecules increase rapidly; the repulsing interactions involving apolar side-chains between L-valine moleculeshave little fluctuate. By the present of ethanol, attractions arising fromhydroxyl groups increase obviously, repulsions arising from apolarside-chains decrease.

随溶液中DMF含量的增大，甘氨酸和L-丝氨酸两分子间的偶极吸引作用逐渐增大。L-丝氨酸羟基的吸引作用影响更加明显，因此增加速度较快。L-缬氨酸非极性侧基的排斥作用变化略有波动。

Methods 75 cases bronchiolitis were categorized in two groups, therapy group 38 cases and control group 37 cases, conventional oxygen therapy, eliminating phlegm, anti-whezing and anti-virus were given in two groups, Montelukast was appendant in therapy group, to observe the time needed in improving the signs and symptoms of the bronchiolitis.

方法75例毛细支气管炎患儿随机分为治疗组38例和对照组37例，两组病例均给予常规吸氧、祛痰平喘、抗病毒等综合治疗，治疗组加用孟鲁斯特钠，观察症状、体征改善时间。结果治疗组7天治愈率明显高于对照组(P.01)差异具有统计学意义。
