查询词典 key chains

相比较而言，β片层具有更好的可延伸性，相邻的由氨基酸残基形成的肽链反向平行排列，同样以 C=O 和 NH 基团之间的氢键连接。

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。

From the equilibra configures obtained during simulating, it was suggested that there is mainly chaintype structure in the LiBO〓 melt, and the dominative variations during the process of being fused may be the decomposition of the long chains, then large member of nonbridge oxygen was come into being in the shorter chains resulting from the decommission.

模拟得到的二硼酸锂熔体中，三配位和四配位的硼氧结构共存，其间相互结合成环状结构；而在偏硼酸锂熔体中没有发现四配位构型，由平衡构像分析，该熔体中可能以链式结构为主，熔化过程中主要的结构变化是长链的分解，分解产生的短链结构产生了大量非桥氧。

But the situations in diatomic chains are more complicated than those in the mono atomic chains.

不同的是，双原子链的情况更加的复杂。

通过电镜观察发现，sPS粒子是许多小粒子的不规则聚集体，初级粒子的大小为1～2μm，而凝胶呈网络状结构。

In this study, main chain of 4,4'-Biphenol combine different side chains to discuss polymer ~ polymer which synthesizes by the difference of structure of 1-Bromobutane、1-Bromoocatane、1-Bromododecane.To examinate luminance property and judge the correction for the structure of polymer ~ polymer by FT-IR、NMR-1H、UV、PL, in the meanwhile,to investigate into radiation wavelength under the condition of different side chains.

中文摘要 1。本实验是利用4，4'-Biphenol为起始物，与Allyl bromide反应，产生丙烯基芳基醚化合物，再利用克莱森重排反应将丙烯基转至邻位，然后在将OH基转变为不同链长的烷基醚合成出聚合物耤I），以FT-IR、NMR-1H、UV、PL测定其发光性质及判断产物结构是否正确，并探讨化合物在不同侧链之条件下，比较其放射波长。

Block-copolyimide film from pPDA/ODA-PMDA was studied by TEM, SEM, PLM, ultra-deep three-dimensional microscope, TMA, and WAXD, which showed that the extensile strength and modulus of b-PI film were higher than that of irregular copolyimide film. It was also revealed that there was a large amount of crystallite formed in b-PI film, which was mainly attributed to its chain structure: rigid pPDA-PMDA chains were easy to form crystal nucleus because of phase separation, based on which semi-rigid PMDA-ODA molecular chains began to crystallize.

以pPDA／ODA-PMDA型嵌段共聚酰亚胺薄膜为对象，借助TEM、SEM、PLM、超景深三维显微镜、TMA、WAXD等手段，研究结果表明：b-PI薄膜的拉伸强度、弹性模量均高于无规共聚酰亚胺薄膜；b-PI薄膜中形成了大量的微晶，这是由于刚棒状的pPDA-PMDA分子链段因相分离容易形成晶核，然后半刚性的PMDA-ODA分子链段以PMDA-pPDA为晶核进行晶体生长造成的，而且ODA-PMDA分子链的结晶和酰亚胺化反应基本上是同步进行的。

It was found that the effect of side groups on the characteristic ratios of mean-square radius of gyration is obvious for the short PDMS chains, and the confomational parameters 〈S^2〉/M of the larger chains about 7.76×10^(-3) nm^(-1), which agrees with the experiment data.

研究结果发现PDMS侧基结构对其短链的均方回转半径特征比影响较大，而长链时构型参数〈S^2〉/M值仍趋向于7.76×10^(-3)nm。^(-1)，与实验结果一致。

It should be noted that the authors consider here only industry value chains terminating with the consumer, as opposed to intermediate goods value chains.

应该指出的是，作者在这里只考虑产业价值链与消费者终止，而不是中间产品的价值链。
