查询词典 aggregates

The possible mechanism was discussed. These bowl-shaped aggregates are promising candidates for nano reactor or drug carrier.4 2,7-dimethylene-1,4,6-trioxaspiro[4, 4]nonane with two vinyls was prepared to be used as electron-donor and crosslinker. The ATRP of this crosslinker and excess methylacrylate (used as electron-accpetor) was proved to mainly form homopolymers. With the chain-transfer agent S-1-Dodecyl-S\'-(α,α\'-dimethyl-α-acetic acid)trithiocarbonate, the copolymerization of the spiro hydrocarbon, maleic anhydride and MA by RAFT method produced star PMA.

这些由聚电解质复合物自组装形成的聚集体，在微反应器和药物释放等领域具有潜在的应用前景。4合成了双乙烯基的2，7-二亚甲基-1，4，6-三氧杂螺环烷，作为给电子单体和交联剂，与吸电子单体马来酸酐或过量的丙烯酸甲酯形成电荷转移络合物共同聚合，尝试了用ATRP和RAFT方法一步法合成星形聚合物。

Using a model of concrete in which the aggregates are spherical and nonconductive particles, the ratio of the interfacial transition zone electrical conductivity and the matrix electrical conductivity σ_/σ_ were calculated.

利用一个将骨料看成非电导球形颗粒的混凝土模型，计算了界面过渡区的电导率与水泥浆基体电导率的比值。

Confocal laser scanning microscopy used to localize the hsp70 protein in oocytes and embryos revealed that the distribution of hsp70 in the ooplasm of immature and mature oocytes is unaffected by exposure to decreased or elevated temperatures and that this protein was closely associated with the meiotic spindle indicating its possible role in stabilizing this structure, hi eight-cell embryos derived under control conditions, hsp70 was evenly distributed in the cytoplasm but appeared as aggregates in some embryos exposed to elevated temperature.

此蛋白均匀地分布在两种细胞的胞浆中。此形态特点与减数分裂期纺缍体有关，由此表明hsp70在中期Ⅱ期，具有稳定这种结构的作用。在对照组8细胞胚中，hsp70均匀地分布在胞浆中，而在处理组一些胚胎内，hsp70则发生凝集。

The results showed that the CH2-CH2 bonds in principal chains, especially when oxidized, were the weakness of the system, while the oxygenous base aggregates, i.e. and were produced.

计算结果和实验数据显示，主链上的CH2-CH2链节为整个体系中的薄弱环节，氧化后该链节变得更不稳定，而且氧化后Parylene C膜主链上生成了、等含氧基团。

Based on these observations, we propose that the periplasmic proteins have been evolved to resist the formation of aggregates when subjected to various denaturing conditions and molecular chaperones may thus not be needed in periplasm.

根据这些发现，我们提出假说：膜间质蛋白在恶劣环境条件的选择压力下进化出对各种变性条件所诱导聚集的抗性，而不需要分子伴侣蛋白的有效保护。

Use of secondary aggregates, in preference to quarried minerals, in civil construction is commonplace.

利用次生材料替代矿物集料已在土木工程中得到广泛的应用。

The results indicated that these surfactants were soluble in SC CO〓 and could form surfactant aggregates, which can solubilize significant amounts of water.

相态结果表明，这些表面活性剂能够溶解在SC CO〓中，并且能够形成增溶一定量水的表面活性剂聚集体。

The reason is probably that the aggregates with low aggregation number start to form at~I, which are not capable to solubilize water. Water solubilization starts only when the aggregation number of reverse micelles is high enough, which occur at~W, the concentration is much higher than~I.

可能因为碘光谱法测得的是开始发生聚集时的cmc，这时聚集体较小，对水无增溶能力；只有当聚集体随浓度升高而长大到一定程度时，才能开始增溶水。

The study of molecular aggregates is an important branch of supramolecular chemistry.

分子聚集体的研究是超分子化学的重要内容之一。
