链段运动 meaning in Chinese

segmental motion
sub-chain motion

With increasing rearrange time , number of proton hopping decreases a little
而随着链段运动恢复时间的相对增加，质子的跃迁数略有下降。
The above phenomena could be explained from the following reasons : ( 1 ) baso4 particles did n ' t hinder macromolecular single bonded internal rotation
这说明baso _ 4对聚合物大分子的单健内旋转运动阻碍性较小，并不影响聚合物大分子链段运动。
Structures of the camp fibers were also discussed . the results showed that the hydrogen bonding between the pva and caa damaged the regularity of crystalline field and the crystallinity of the fibers reduced . the cluster structures of each phase in the blend were changed and movement of the molecular chain segment was reduced
对camp纤维结构的研究表明， pva与丙烯酸-丙烯酰胺共聚物( caa )共混后，大分子间的氢键作用破坏了pva晶区结构的规整性，导致pva在camp纤维中的结晶性明显减弱；两种共混组分的聚集态结构发生变化，大分子链段运动受到影响。
