查询词典 sample distribution

SEM result showed that the sample had uniform phase distribution and smooth surface at dried state as well as interpenetrate network structure at hydrogel state. It was seen from the swell ing behavior curves that groups T1, T2 and T3 swelled rapidly within 10-30 minutes, and formed elastic composite hydrogel pipes. In addition, the expanding ratio of inner and outer diameter of the tube was 20%-30% and 100%-120% with swell ing, respectively. The equil ibrium water content of the hydrogel pipes increased with increase of collagen composition. Three groups of samples were immerged in PBS solution contained 2 mg/mL lysozyme at 37 for 1 month, their nozzle cracked, their wall became thin and more transparent. And also, there was small floc deposited on the tube surface.

扫描电镜观察到液氮脆断的人工泪小管内部成分分布均匀，内外壁表面平整，冷冻干燥的人工泪小管断口呈凝胶态的互穿网络结构。3 组不同成分的人工泪小管在PBS 溶液中浸泡30 min 后均快速吸水溶胀，外径扩大100%～ 120%，内径扩大20%～ 30%，并且随胶原含量增高，溶胀速度增快，平衡溶胀率增大。3 组人工泪小管在37℃含2 mg/mL 溶菌酶的PBS 液中浸泡1 个月后，表面有部分细小絮状物，管口开裂，管壁变薄，透明度增加。
