There are usually several vibration modes participating in heliostat's response to wind induction. The complete quadratic combination method can take the modes' coupling effect into account. The result is precise, however the computation work is heavy. Therefore, the proper orthogonal decomposing stochastic wind field was proposed to be applied in computation of heliostat's response to wind induction.

定日镜结构风振响应中有多个振型参与，利用完全二次型组合法可以考虑各振型间的耦合作用，得到精确结果，但计算量很大，因此提出将随机风场本征正交分解技术运用到定日镜结构响应计算中。

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.
