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 entire LTR 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。

对缺硼的豌豆植株去顶也可以导致细胞分裂素水平的增加，但变化的幅度明显小于对照条件下的变化，表明由于缺硼影响了激素的水平从而减弱了顶端优势。

Further picosecond PL studies on dendronized PFs show that the fluorene-based emission in dilute solution follows a single exponential decay, whereas those in thin film decayed in a multi-phase manner and the lifetime prolongs with the generation of dendronization. These observations are discussed in terms of dispersive transport happening between adjacent chains in film. The dispersive relaxation can be controlled by site isolation of bulky dendrons. Our results prove that dendronization is highly effective in controlling the inter-chain interactions of fluorene-based polymers.

不同代数树枝化聚芴的时间分辨荧光动力学研究结果表明，溶液状态下的发光为单指数衰减行为，而薄膜状态下的发光为多指数衰减行为，且其发光寿命随树枝化代数增加而增长，表明树枝化基团抑制了邻近的聚芴分子之间能量传递所致的激发态能量耗散。
