摘　　要：本文运用紊动扩散方程和自模理论,对强迫掺气中通气槽挑射水流空腔区水股断面含气浓度分布进行了理论探讨,并提出了射流挟气量的计算公式,所得结果与实测值吻合良好。In this paper,the air concentration distribution over the cross-section of the free nappe above the aerator device is investigated theoretically by using turbulent transport equation and self-preservation theorem.A formula for calculating the self aeration capacity of the free nappe is derived.The calculated results agree well with the measured data.
