结果表明：循环出水显著提高了对BOD5、COD、SS和NH+4-N的去除率，且对BOD5的去除满足Monod方程；大部分NH+4-N的去除率与其表4-N被硝化，对NH+面负荷率呈线性关系；随着硝化反应的进行，碱度减少，pH值不断降低；循环出水可引入部分氧气，延长了污染物和附着于植物根系微生物的接触时间，提高了对污染物的去除率。

The nitrogen removal experiment implies that the nitrogen removal efficiency is very high. The ratio of NH_4~--N/TN is approximately equal to the ratio of TN removal. TN removal efficiency is mainly affected by the influent NH_4~--N concentration, and the optimal TN removal efficiency can be prejudged by the ratio of influent NH_4~--N/TN.

Golden-crowned kinglets tolerated colder temperatures in helox than ruby-crowned kinglets, and this difference was not a function of mass or thermal conductance, as these did not vary significantly between species. Msum in golden-crowned kinglets (2.51 ml±0.32 ml O2min-1, n=11) was significantly greater than that in both male (2.27 ml±0.25 ml O2min-1, n=13) and female (2.05 ml±0.18 ml O2min-1, n=13) ruby-crowned kinglets, suggesting that metabolic differences may account for differences in cold tolerance.
