| 摘 要： | 分析对比作图法、线性回归法和非线性回归法计算曝气设备清水氧传递系数(KLa)各自的优缺点。指出在实际测定曝气设备性能中，使用非线性回归法计算KLa更加可靠．而且可以使测试过程更加容易控制。所以在实际测试过程中，推荐使用非线性回归法计算KLa。

| Abstract: | Compare of estimating the apparent oxygen transfer coefficient, \%K\-La\% in clean water by linear regression method with nonlinear regression method was carried out in this paper. It was found that \%K\-La\% estimated by the later is more accurate, and it would make the control of the test much easier. So nonlinear regression method is recommended to estimate \%K\-La\% in assessing the performance of aerators. |
