This model predicts an increased electron density with an increasing channel depth in subthreshold region or mild inversion region.
该模型预测的电子密度增加，增加航道水深在亚阈值区或温和反转区域。

The channel friction is importance parameter of hydraulic analysis, a channel friction parameter inversion method based on Kalman filter with unknown parameter vector is proposed.
河道糙率是洪水水力计算的重要参数，引入控制论理论，应用带参数的卡尔曼滤波法进行河道糙率反演分析。

When decay rate in the coupling channel is greater than that in the probe channel, the incoherent population pumping in the probe channel can create the gain without inversion.
