各混养组COD值和水层细菌数量相互差异不显著，但各混养组均显著低于单养组（t检验，α<0.05），混养围隔水体有机质含量明显低于单养；

The value of COD and the number of bacteria in the water of polyculture enclosures were significantly lower than those in monoculture ones ( t-test ,α < 0.05 ), showing that the amount of organic matter in the water of polyculture systems was less than that in monoculture one .

在支出项目中，单养组和混养组收获的养殖生物分别占N总输入的25.0%和44.4%~51.5%，占P总收入的11.2%和25.1%~31.8%；

Among the output items , the biomass harvest comprised 44.4 % ~ 51.5 % of total nitrogen input and 25.1 % ~ 31.8 % of total input phosphorus in polyculture systems , 25.0 % and 11.2 % for monoculture systems ;

在单养条件下，受到UV-B辐射的石莼和微藻，可溶性蛋白含量和Chl-a含量有显著的下降趋势，而ROS含量、H2O2含量、MDA含量和SOD活性有明显的上升趋势。

The soluble protein content and Chl-a content showed decreasing trend , but ROS content , HaOa content , MDA content and SOD activity showed increasing trend in culture alone under UV-B radiation treatment .
