The total flood volume is reduced, the flood duration is prolonged, the peak flow is decreased dramatically, and the flood hydrograph is characterized by the rapid rise and mitigatory recession;

洪水总量减少，洪水历时延长，洪峰流量显著降低，洪水过程线表现为涨洪陡、落洪慢的特点；

The conditions of synthesis of APG were optimized through orthogonal experiment. APG's surficial chemical properties were measured. APG's mitigatory effect on Aluminum was studied in base medium.

通过正交实验优化了十二烷基葡萄糖苷（APG）的合成条件，测定了APG的表面化学性能，并探讨了APG在碱性介质中对铝的缓蚀作用．。
