Laguerre-Gaussian(LG)模光学涡流拓扑指数位错实验研究了带有相反拓扑指数的Laguerre-Gaussian(LG)模间的相互作用,发现含有相反拓扑指数的两个LG模在传播过程中其光场发生变化,观察到随着传播距离的增加,两个LG模的中心位相奇点会逐渐连成为一个弧形暗线形状.实验上验证了带有相反拓扑指数的光学涡流中的螺旋位错在传播过程...
System comparison between shelf and basin would be helpful to promote understanding of the regulation mechanism of POC export in the tropical marginal seas. Keywords: POC export efficiency; ocean net primary production; satellite remote sensing; northern South China Sea 1. Introduction The ocean is ...
