查询词典 segments

However, more perfect structure of PEO segments is formed when the system exits in semicrystalline-semicrystalline state.3 When the composition of hard segments is 30%, the crystallizability of PETsegments exerts strong influence on the nucleation mechanism and growthdimensions of soft segments.

PEO嵌段的晶体尺寸小，结构不规整，结晶度低；当体系处于结晶—结晶态时，PEO嵌段的晶体结构比较规整，而且此时软段长度对其形态影响也比较大。3硬段含量为30％时，它的结晶与否直接影响软段晶体的成核及生长方式。

For the PUU/BO-g-VER (n-butanol graft VER network)hybrid film, the miscibility between the soft and hard segments in PUU phase was improved byadding the BO-g-VER network into PUU, resulting in remarkable reinforcement effect andgreat improvements of mechanical properties for the films. In the PUU/200-g-VER [Mn: 200,poly graft VER], the 200-g-VER network had considerable compatibility withboth hard segments and soft segments in PUU phase, then good reinforcement effect wasrealized, giving rise to higher tensile strength and elastic module, lower elongation at break ofthe hybrid films.

由于BO-g-VER与PUU硬段具有较好的相容性且促进了PUU软硬段间的微相混合，导致PUU／BO-g-VER hybrid膜的力学性能有较大程度的提高，体现了明显的增强效果。200-g-VER(分子量为200的单官能团聚醚接枝VER)与PUU软硬段均有很好的相容性，因此PUU／200-g-VER hybrid有较好的增强效果，使胶膜的拉伸强度和弹性模量提高，断裂伸长率下降。

Homolog analysis confirmed 16 differentially expressed segments. 15 of them were similar to the human genes already known, including ANXA2, TUBB, PKN2, GNAS, EEF1A1, SSR2 and RPLPO et al. Only one segment had partial homology to known human genes. This segment was supposed to be the new EST segments which might not have been cloned.
