19. The application of modified nylon 66 cord inLTR tire was investigated and compared to that of HMLS polyester cord.
研究改性锦纶66帘布在半钢子午线轮胎中的应用,并与高模量低收缩聚酯帘布进行比较。
20. A recombinant pl asmid (designated as p8.0) was obtaining by ligating these three fragments. The p8.0 was subcloned into a plasmid (designated as p8.2) containing entireLTR of EIAV DLA. The complete nucleotide sequence of DLA strain of EIAV was determined by sequencing the p 8.2. The purified p8.2 was used to transfect donkey leuko cyte cultures.
将此8.0kb EIAV全基因再亚克隆到含有一完整EIAV DLA株长末端重复序列的质粒中,获得一含有EIAV驴白细胞弱毒前病毒全基因的重组质粒,将其命名为p8.2,经核苷酸序列分析,证明p8.2含有EIAV前病毒的全基因。
