查询词典 spindle fiber

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.

结果 采用神经管植块法培养的神经嵴干细胞，免疫细胞化学染色呈现nestin及P75双阳性，将其接种在壳聚糖纤维支架材料上，可见神经嵴干细胞贴附于壳聚糖纤维上生长；S-100免疫细胞化学染色显示，S-100阳性细胞突起的末端呈扁平状膨大；扫描电镜显示，壳聚糖纤维上的躯干神经嵴干细胞为梭形，呈现"端对端"、"肩并肩"排列，伸出爪形伪足贴附于壳聚糖纤维上。

In the production processes, the materials were arranged reasonably and the treating after the fiber dying was paid some attentions. It used the "light weight, low speed, large ratch, more carding and small dropping" principle in the carding process, and the "tight ratch, light weight, low speed" principle in the drawing and roving processes. The break ratch was let out properly in the spinning process. In the double twisting process, the differences of yarn doubling tension and spindle speed were reduced, the twist distribution was evenly in the compound yarn accordingly.

生产中，注意原料的合理搭配和染色后处理，前纺梳理工序采用"轻定量、低速度、大隔距、多梳少落"的原则，并粗工序则采用"紧隔距、轻定量、低速度"原则，细纱工序适当放大后区隔距，倍捻时尽量减少并纱张力差异和锭速差异，提高股线捻度分布的均匀性。
