Results based on experiment and measurement data indicate that, when 244 nm argon ion laser emits 40 mW UV light, the curve of refractive index changes in single mode hydrogen loading fiber is exponential type (Ac=1.632×10-6 t 0.76912), exponential growth is obvious in the beginning, a very good linear region is following, and then refractive index increments reach saturated.

结果表明， 244 nm氩离子倍频激光器输出光功率为40 mW时，普通载氢光纤光致折射率变化量随曝光时间总体上呈现指数分布关系Ac=1.632×10-6 t 0.76912；在曝光时间较短时，造成的光栅强度较弱，光致折射率变化量有明显的指数增长趋势，之后是一段较好的线性区域，这时两个测量模型的结果得到了很好的印证，随着曝光时间的继续增加，光致折射率变化量达到饱和。

Three RNAi target sites (named as Abil1, Abil2, Abil3) targeting the E3B1 (NCBI: NM-024397), an identified target sites and positive control GAPDH-A were selected. The pGenesil-1 eukaryotic expression vectors with the neoR mark and GFP green fluorescent mark were selected to construct E3B1 RNAi plasmid. The effect of RNAi targeting various sites on E3B1 genes expression was evaluated by testing the transfection efficiency with fluorescence microscope and western blot. The most effective siRNA in inhibiting E3B1 genes were screened. The most effective siRNA in inhibiting E3B1 genes screened and used to transfect the neuronal cells. After that, the inhibitor of axon growth was added and the axon growth was observed. Result: The siRNA expressing plasmids targeting the E3B1 were constructed successfully.
