水体中饱和溶解氧的求算方法探讨

Study on Calculation Method of Saturation Values of Dissolved Oxygen in Waters

根据标准大气压和不同水温下的饱和溶解氧浓度值回归出饱和溶解氧浓度值随水温的变化公式，并探讨了水体中饱和溶解氧浓度与大气压的关系，结果表明，计算结果与实测值的相对误差在±０．５％范围内。

A formula between the saturation values of dissolved oxygen and the water temperature was obtained,according to the saturation values of dissolved oxygen with different water temperature under a total pressure of 1013hPa.Relationship on the saturation values of dissolved oxygen and the atmospheric pressure was approached,and the results show that error rate between the calculation value and the measuring concentration is ±0.5%.
