分子链段 meaning in English
molecule segment
Examples
- The mechanism of photoalignment is that the selective photoreaction broke out on the surface of the polymer under the irradiation of linearly polarized ultraviolet light ( lpuv ) . the orientational alignment of molecular chains induces lc alignment in a certain direction
光控取向的原理是在线偏振紫外光作用下，光敏聚合物侧链定向光交联，出现分子链段的指向有序分布，从而诱导液晶分子排列。 - Above all , this paper gave a qualitative analysis to the macromolecule mechanism of the macroscopical viscoelastic phenomenon of high polymer in exordium and pointed out that both creep and relaxation are the gradual process of response to the external force , which is performed by all scales of molecule units with different deformation time
论文首先在绪论部分定性地分析了高分子宏观粘弹性现象的高分子机理，均是运动时间不同的各级分子链段逐渐对外力做出响应的过程。在实验的基础上，对单轴pmma试件的蠕变型本构关系进行了研究。 - Poor thermal stability as a bottleneck has limited the development of liquid crystal photo - alignment technique . the intrinsic reason is that the photosensitive polymer has large space resistance and decreases the reaction degree of the directional photo - polymerization . the effective solution is focused in the increase of orientational order of photo - alignment film
光控取向技术瓶颈问题是稳定性差，其根本原因是光敏高分子空间位阻太大，定向交联的反应度太低，有效解决方法应是降低位阻，提高定向交联度和取向膜分子链段的有序度。
