查询词典 key chains

Adjacent helical chains are racemic. The Ag atom is linked to two nitrogen atoms of the 2-pyridyl and 4'-pyridyl groups from two different 2,4'-bpy ligands as well as to the oxygen atom of the counterion. In 17 and 19, the adjacent helical chains are linked to wavy two-dimensional network structures by the nitrate counterions.

相邻的螺旋链间是外消旋的，Ag 原子与分别来自两个不同2，4'-联吡啶的2-吡啶基和4'-吡啶基的氮原子以及阴离子的氧原子配位，在配合物17和19中，相邻聚合螺旋链被硝酸根离子桥连接起来，变成了一个波浪形的二维网络结构；配合物18是首次通过无桥连配体支持的Ag ××× Ag键将相邻螺旋链连接成二维非穿插的网络结构。

Beta-thalassemia major is a serious hereditary hemolytic anemia which does great harm to human being.It is a monogenic disease characterised by a reduced synthesis of beta-globin chains,which dues to the Doint mutation or deletion of beta-globin gene and its control region.It not only decreases the hemoglobin level,but breaks the balance of alpha/beta synthesis ratio.The major cellular pathogenetic mechanisms in beta thalassemia are based primarily on the deleterious effects produced by the accumulation of the excess alpha globin chain.These excess alpha-globin chains cannot form stable tetrameric structure and deposit in erythroid cells.They cause large ineffective erythropoiesis on their own,accelerate red cells destruction,and lead to hemolysis.

地中海贫血是一种对人类健康危害严重的遗传性溶血性贫血病，是因β-珠蛋白基因及其调控序列的点突变或缺失致使β-珠蛋白肽链合成减少或完全停止，这不仅使患者血红蛋白水平降低，而且使原来在数量上与之持平的α-珠蛋白肽链相对过剩，这些相对过剩的游离α-珠蛋白肽链并不能形成稳定的四聚体，它们沉积在红细胞中导致了大量无效红细胞生成和红细胞寿命缩短，引起了严重的溶血性贫血。

The apparent degree of network chains for the different swollen extent of the same unswollen hydrogel sample increased linearly with the increase of swelling ratio, however, the apparent modulus did not decrease monotonously with the increase of swelling ratio. Furthermore, the dependence of apparent degree of network chains on swelling ratio had nothing to do with the swelling agent. The above results reflected the changes of entanglement and the contribution of entanglement under different swelling ratio, and the results could be explained with the theory of Flory-Erman's constrained junction model and LangleyGraessley relation.

发现同一水凝胶样品的不同溶胀程度试样经应力应变测试得出的表观网链密度随体积溶胀率的增加而线性增加，等效模量并不随溶胀程度的增加而单调减小，而表观网链密度的溶胀程度依赖性与所选用的溶胀剂无关，该结果反映了不同溶胀程度下缠结的变化及缠结对弹性的不同贡献，并可由Flory-Erman的constrained junction模型及Langley-Graessley公式得到解释。

Car makers use these belts instead of more durable chains because chains are noisier and cost more to manufacture.
