Recent experiments on independent tuning two color and three color femtosecond laser detection technology indicated that study of the ultrafast process of photosynthesis micromechanism using multi excited state spectroscopy, selectivity ultrafast time resolved spectroscopy and process control femtosecond photochemistry reaction dynamics can be carried out effectively.
对独立调谐的双色、三色飞秒激光探测技术进行了探索性研究,结果表明,利用多激发态光谱学、选择性超快时间分辨率光谱学和程控飞秒光化学反应动力学可有效进行光合作用微观机理的超快过程研究。
two better ones out of seven supported catalysts were selected for carbonylation of ethyl alcohol. factors effecting the conversion and selectivity for the reaction have been studied and the valence state of active species and the acidity of carrier have also been examined.
本文由七种负载型催化剂中选出两种比较好的乙醇羰化催化剂,研究了影响反应转化率和选择性的因素,考察了活性组份的价态和载体的酸性。
