您要查找的是不是：
- A short polymeric chain of two to ten nucleotides. 低（聚）核苷酸由两个到十个核苷酸构成的一条短聚体链
- The Ru complex was intrduced into the polymeric chain by coordination reaction of the polymer with the small molecular Ru complex. The corresponding Ru-containing polymers were named as PV-Ru (PV and Ru-1) and PA-Ru (PA and Ru-2). 再将一定量的PV与Ru-1、PA与Ru-2反应制备了两个系列同时含钌配合物染料和乙烯基咔唑的双功能聚合物光伏材料PV-Ru和PA-Ru。
- The molecular weight increased by degrees along the electric field.The transparent layers had more regular microstructure and polymeric chain distribution than the hazed layers. 透明层即透光率较大的层相比于雾度层微观形貌更加规则，链段有序度增加。
- a short polymeric chain of two to ten nucleotides 由两个到十个核苷酸构成的一条短聚体链
- In order to control the distribution of composition among the polymeric chains, different co monomer was fed into the reactor at a varied rate. 控制共聚单体的进料速率，不同的共聚单体对制备聚丙烯腈原丝的聚合反应有不同的影响。
- Its long molecules, consisting of tens and hundreds of thousands of methylene groups (!CH2!), cannot exist as long stretched polymeric chains, which might be called a “primary structure. 它是一个大分子的化合物，是由数万数千万的二次甲基（-CH2-）组成的，不能长期以高分子链的延伸存在，这可以称之为“基本结构”。
- The chain has fallen foul of plants in the water. 链条已和水中的植物缠绕在了一起。
