摘要
首先正确估计出样品ＢＯＤ_５浓度范围，并测定稀释水的溶解氧，然后根据稀释倍数公式计算三个适当的稀释倍数。本方法省时、可靠、适用性强，能够确保ＢＯＤ_５样品分析一次成功。在ＢＯＤ_５样品分析中具有广泛的应用价值。
Firstly the concentration area of BOD_5 in samples is evaluated correctly. The desolved oxygen in diluting water is detected. Then 3 propable dilution ratios are calcalated according to dilution formula.This method is time-saving,reliable, suitable to wide application, and the analysis of BOD_5 samples is oncetime successful.
