摘　　要：本文提出用快速法测定出COD_(Cr)值后,按稀释倍数通式c_n=COD_(Cr)/6.5×2^(n-1))(n=1,2,3)计算出三个适当的稀释倍数.与其他方法相比,本方法简便、可靠,普遍适用,可保证样品BOD_5分析一次成功.在BOD_5分析监测中具有实际意义和推广价值.Presented in this paper is a simple, speedy and reliable method for. determining BOD5 in. water samples. After the values of CODcr have been determined, three proper diluted mulples are calculated in accordance with the general formula for evaluating the coefficients of dilution:Cn = CODCr/6.5 ×2n-1 (n= 1,2,3)
