第二步策略是减小两个传导带态的能量落差，这样一来受激发电子就更容易溢入光子释放态。

The second strategy was to lower the energy difference between the two conduction-band states so that excited electrons would be more likely to spill over into the photon-emitting state.

现对跌坎式底流消能工消力池内水流流态的演变进行了初步分析，随着入池能量的变化，消力池中会产生混合流、淹没混合流、淹没底流以及远驱底流流态。

With the change of in-take energy, the flow patterns in the stilling basin are:mixed flow, submerged mixed flow, submerged bottom floor and far-forth drove bottom floor.
