对试验系统采集到的焊接电弧声进行了小波包多层分解，并利用周期图法、Welch 平均法及AR模型法，对各频段信号进行功率谱估计。根据不同谱估计方法的对比结果，提出小波包分解结合Welch 平均法对焊接电弧声进行功率谱估计的新方法。通过对几种规范与飞溅率下的电弧声功率谱的初步分析，发现其功率谱分布具有一定的规律性，并且不同频段谱峰值及其对应频率与焊接飞溅具有相关

0Mg/L 6-benzylaminopurine was the optimal concentration of shoots quantity inducing which frequency of inducing shoots and number of shoots per explant were 100% and 11.1 respectively. 0.5mg/L 6-benzylaminopurine was the optimal concentration of shoots length inducing which average length of shoots was 12.0mm. Explant size had significantly effects on direct shoots quantity and length induction. When complete cotyledon used as explant, frequency of inducing shoots, number of shoots per explant and average length of shoots could approach to 100%, 6.7 and 17.1mm respectively. 2.0mg/L silver nitrate could significantly increase shoot quantity induction, both frequency of inducing shoots and number of shoots per explant could be as high as 97.2% and 4.2 respectively. But silver nitrate also could restrain shoots elongation.
