【摘要】 本文在概括前人对水工泄水建筑物大气复氧研究成果的基础上，通过对天然观测资料的分析和室内的系统试验，指出除非饱和复氧外还存在超饱和复氧状态，两者的复氧规律是不同的．在设计水工泄水建筑物时，需选用恰当的型式和运用方式，利用不同的复氧规律满足不同水体对复氧的不同要求，在增加水体环境容量的同时又为鱼类的生长提供合适的条件．更多还原

【Abstract】 Based on the previous research’on the reaeration of sluice structures and the analysis of field data and laboratory system experiments,this paper indicates that there ealsts a state of supersaturation reaeration which follows the laWs differ from that of nonsaturation reaeration.Hence,it is necessary to choose.a suitable type of sluiCe structure and operation program,to meet the reaeration requirements of varied water body,in order to increase the environmental capacity of water and improve living condition for fish.更多还原
