The result of tensile test indicated that the residual γ-butyrolactone content in casting PVF film was an important influencing factor on the succeeding uni/bi-axially orientation stretch of the

通过拉伸测试可知，流延薄膜中γ-丁内酯的剩余含量是影响薄膜能否进一步拉伸的关键因素。

After HRP application, HRP labelled cells were distributed in the nucleus of trapezoid body , lateroventral periolivary nucleus , retrotrapezoid nucleus , lateral paragigantocellular nucleus and lateral reticular nucleus . The findings demonstrated the existence of neural structural relations between the chemosensitve areas and the Tz, LVPO, NRT, LPGi and LRt, and revealed that these nuclei might participate in the mechanism of central chemical regulation on respiration.

观察到用浸有HRP的滤纸局部敷贴于延髓腹外侧表面化学感受区后，在延髓斜方体核、外周橄榄腹外侧核、斜方体后核、巨细胞旁外侧核和外侧网状核等核团找到HRP标记的细胞，表明上述延髓内部核团与腹外侧表面化学感受区之间存在神经结构联系，提示延髓腹外侧表面化学感受区对H〓等物质的化学感受机制可能与上述核团神经元伸向该区的突起有关。

The polyurethane hot-melt adhesive film was prepared by casting process and the effects of polyether diol trpe,chain exlender amount andpolyol molecular weight on tensile strength,tensibility and hardness were studied.

采用流延法制备聚氨酯热熔胶膜，对影响聚氨酯热熔胶膜的拉伸强度、断裂伸长率、硬度的几个因素：聚醚多元醇类型、扩链剂用量和聚醚多元醇的分子质量等进行了研究。

Advances of extrusion equipment for plastics film, including blown film lines, biaxially oriented film lines, calendered film lines and various accessories such as dies,air rings,screenchangers,melt bumps, are introduced.

介绍了近年来塑料薄膜生产设备的最新进展，包括挤出吹塑薄膜设备、双向拉伸薄膜设备、流延设备以及各种辅机，包括机头、风环、牵引、换网器等的技术进展。

This is a border road mainly for military use. Tortuous and zigzagging, it extends to the distant end.

这是一条以军用为主的边境公路，弯曲盘延，伸向遥远的尽头，第一眼看到时，我不禁为它的险峻倒吸一口凉气！
