新型二氧化碳点阵激光治疗系统的研制

Study on Chlorophyll and Photosynthetic Characteristics of Pepper Inbred Lines

目的：设计国内领先的新型二氧化碳点阵激光治疗系统,实现准确控制点阵激光的输出,从而得到良好的临床治疗效果。方法：利用单片机控制激光电源,通过激光功率反馈系统、独特的光束传输及点阵系统保证点阵激光的剂量,使用激光瞄准器将激光准确定位,最终得到准确的点阵激光。结果：新型二氧化碳点阵激光治疗系统可对准患者操作部位进行瞄准定位,具有2～3种焦距的镜片,并可实现矩形、三角形、圆形等图形点阵激光。结论：该系统成功克服国内激光点阵输出比较粗糙、不能准确控制点阵输出及色沉严重等缺点,得到良好的临床治疗效果。

The pepper leaf chlorophyll and photosynthetic characteristics of 17 inbred lines by independent selection were studied. The results showed that the different inbred lines of chlorophyll content had significantly difference. No. 68 was significantly higher than that of the other 14 inbred lines,No. 55 was significantly lower than the other 15 inbred lines, Chlorophyll content in the order of 68〉47〉66〉62〉63〉60〉61〉64〉56〉67〉65〉48〉59〉58〉57〉69〉55; different inbred lines of photosynthetic rate in the order of 68〉57〉60.〉48〉58〉47〉62〉63〉64〉65,65 inbred lines maximum photosynthetic rate was significantly lower than the other 7 inbred lines,the remaining 9 inbred lines were not significantly different.
