In the study of the water oxygen resume, start off the mechanism of the atmosphere oxygen resume, the paper first poses the atmosphere oxygen resume equation and oxygen resume coefficent calculation formulation of the static state water. The number of the progressing of the Blak-phelps equation is made certain, and the atmosphere oxygen resume equation and coefficent are ensured in both conditions of considering the floor reflection and unconsidering the floor reflection.
在对湖库水体复氧研究中,从大气复氧的机理出发,首先提出静态水体的大气复氧方程和大气复氧系数计算公式,其中对Blak-phelps方程级数项项数的确定,不考虑底部反射的大气复氧方程和考虑底部反射的大气复氧这三个问题进行了深入分析,得出相应的结果。
