自从激光问世以来,以其高光亮度、单色性、定向性和超短脉冲性使人们在用激光进行同位素分离、浓缩铀等方面取得了长足的进步,利用超短脉冲激光进行反应动力学研究已开始起步,但是,鉴于能量因分子碰撞而损失,许多研究都是在低气压条件下进行的,以单体直接进行激光液相聚合的例子不多,目前还未见以激光进行阴离子型的聚合反应。我们利用激光能定向离解某一键的特点,以连续输出单模运转的CO_2激光,在未聚焦的情况下,对甲
Since the advent of the laser, great progress has been made in the field of laser isotope separation and uranium enrichment with its high brightness, monochromaticity, directivity and ultra-short pulse. Reaction kinetics has been studied by ultra-short pulse laser Has started to be started. However, due to the loss of energy due to molecular collisions, many studies have been carried out under low pressure conditions. There are not many examples of direct liquid-phase polymerization of monomers by monomers. Up to now, no anionic Polymerization. We use the laser can be a certain direction of the dissociation of the characteristics of a key to continuous output single-mode operation of CO_2 laser in the case of unfocused, a
