Let G be a finite group of Lie type E6 over Fq (adjoint or simply connected) and W be the Weyl group of G. We describe maximal tori T such that T has a complement in its algebraic normalizer N(G, T). It is well known that for each maximal torus T of G there exists an element w ∈ W such that N(G, T )/T ■ CW(w). When T does not have a complement isomorphic to CW(w), we show that w has a lift in N(G, T) of the same order.

通过室内模型试验，以普通尿素（U）、腐植酸包膜尿素（U-HA）和脲酶抑制剂N-（正丁基）硫磷三酰胺处理尿素（U-UI）为研究对象，研究了3种尿素肥料对土壤氮素转化过程的影响。更正研究了尿素肥料对土壤化学（水浸提N-NH4和N-NO3含量）和微生物特性（N2O实际和潜在排放速率、基础呼吸和底物诱导的呼吸、微生物生物量碳、乙烯排放速率）的影响，旨在验证：（i）腐植酸包膜尿素是否具有减少土壤氮素损失的能力；（ii）与合成脲酶抑制剂相比，它是如何影响土壤生物活性的。结果表明，U-HA在减少土壤氮素损失方面具有与U相当的优势，使土壤N-NH4含量增加了35%，硝酸盐含量减少了9%，N2O排放减少了50%。U-HA使土壤基础呼吸提高了10%，土壤微生物群落比活性提高了7%，提供了最高的代谢熵qCO2。与U-UI相比，U-HA主要表现为介于U-UI和U之间的效果。考虑到腐植酸原料成本低，U-HA可以被认为是减少土壤氮素损失的有前景的工具。
