Analyses of spectral structure and surface tension of solutions suggest that the hydrophobic hardrocarbon chain of surfactants was partly included in the apolar cavity of β-CD and the part with the polar head group of hydrocarbon chain located outside the cavity coiled over the top of β-CD, providing an effective protection for RTP.

组成测定表明溶液中形成了稳定的1：1：1/1-BrN：β-CD：AS三元包合物。光谱和溶液表面张力分析显示阴离子表面活性剂的疏水性烷基链有一部分被包合在β-CD空腔内，未被包合部分则绕曲在β-CD腔口处从而为空腔内1-BrN分子的磷光提供了有效保护。

Molecular data place Empetrum and its relatives firmly within the Ericaceae, and in particular within the subfamily Ericoideae, in agreement with phytochemical and palynological data, and there they are best recognized as a separate tribe.

分子证据支持把在Empetrum 和它的亲缘类群放在杜鹃花科Ericaceae内，尤其是Ericoideae亚科内，这与植物化学和孢粉学证据相一致，它们最好作为一个独立的族。

Next, seven of those trimmed molecules combine to form a ring-shaped structure, or heptamer, that captures the two factors and is transported to an internal membrane-bound compartment called an endosome.

之后，七个剪裁过的保护抗原分子会聚集起来，形成一个环状构造，称为「七聚体」，藉此抓住另外两种因子，再一起送入细胞内一个称为「内小体」的膜状构造。

Chiral centers of C5 and C8 are directly constructed in the key step of the diastereoselective propargylation from D--tartrate. The methylation and subsequent methoxycarbonylation result in desymmetrization of the terminal dialkynes. The α,β-unsaturated δ-lactone is synthesized after partial hydrogenation and lactonization.

由非天然酒石酸出发，利用双向非对映选择性的炔丙基化反应，在一步反应中同时构建C5和C8手性中心；然后通过末端炔基的甲基化、甲酯基化，延长碳链并对分子去对称化；内酯化得到关键中间体α，β-不饱和六元内酯，再经多步反应转化得到8-epi--Boronolide。

The results are as follows:(1) immunoreactive neurons of NPY in medulla oblongata of Taihe silky fowl, New jianghan domestic chicken are mainly localized in the inferior olivary nucleus.

结果如下：(1)在泰和乌鸡和江汉鸡的延髓中，NPY阳性神经元主要存在于下橄榄核，网状核及中缝核也少量出现；(2)在泰和乌鸡和肉鸽的小脑中，NPY阳性神经元主要存在于小脑皮质的蒲肯野氏细胞层，且以小叶顶端的蒲肯野氏细胞阳性明显，而小脑皮质的分子层、颗粒层未见阳性反应细胞；(3)泰和乌鸡延髓的网状细胞核非常发达；泰和乌鸡小脑皮质分3层，由外至内依次为分子层、蒲肯野氏细胞层和颗粒层；小脑分10叶，Ⅰ、Ⅱ和Ⅹ为单叶，其余各叶都分为2～3个小叶；(4)非洲鸵鸟迷走神经运动背核和疑核特别发达，孤束核吻侧部不发达。

The results indicate that the PPV oligomer with biphenyl bridge is a cross form between two chains and tortuose derivative in the same chain. It reduces molecular symmetry and weakens %π-π% stacking effect among conjugated molecules in solid. This is perhaps the important factor that light-emitting diodes can increase fluorescence quantum efficiency.

结果表明，联苯桥联后的PPV齐聚物在结构上形成了链间交叉链内扭曲的构象，这种交叉扭曲的构象降低了分子的对称性，减弱了共轭分子在固体中的π-π堆积作用，这可能是减少荧光猝灭效应，提高固体发光器件效率的重要原因。

Along the axis within 2 cm, a hollow gas shell structure is formed.

估算结果为：在轴向2.5~40 mm，径向0~15 mm的区域内，气体分子密度基本在10^16~10^17/立方公分，且在轴向2 cm内基本形成空心的气体壳层结构。

The direct interaction of copper ion with CuZnSOD was studied by fluorescence spectroscopy, and a type of 1:1 stable complex has been generated, which was certified by the quenching experiment of intrinsic fluorescence. The process of the generated complex shown by dynamic analysis of fluorescence quenching, consisted of two steps, in which the first step was a quick association process of double molecules to generate a loose complex, and the second step was a slow process of single molecule, where the loose complex was isomerized into the compact complex.

通过荧光光谱方法研究了这种相互作用，内源荧光的猝灭实验表明Cu(上标 2+)与CuZnSOD形成1：1型稳定配合物；荧光猝灭的动力学分析表明配合物形成过程由两个独立步骤完成：第一步是双分子快速缔合过程，形成了结合疏松的配合物，第二步是单分子慢速过程，即松散的配合物&异构化&成为结合紧密的配合物。
