Results show that floes' VC and D at the surface water were closely related to current velocity; and the peaks of VC lag those of the current velocity. The lag variation during ebb and flood tides is 10-30min and 30-50 min, respectively. Current velocity at 50 cm/s is a turning point of D vs. vertical average current velocity, before the point, Dm increases with current velocity, and decreases after the point. Similarly, VC at 75μl/L becomes a critical point in the surface water, below the point, D increases with VC, and above the point, D stabilizes.Δp is D dependent, larger floes have much lower Δp than smaller floes. Both D and Δp of floes affect ω. In the surface water during spring tide and neap tide, a power exponent relationship exists between Δp and D, and ω and D.
研究表明:①长江口徐六泾表层絮凝体体积浓度主要受水流流速影响,再悬浮现象明显,体积浓度过程线滞后流速过程线,落潮期间滞后10-30min,涨潮则滞后30-50min;②小于一定流速时絮凝体平均粒径随流速增大而增大,大于一定流速时絮凝体平均粒径则随流速增大而减小,徐六泾夫、小潮表层絮凝体在50cm/s的垂线平均流速时出现平均粒径与垂线平均流速关系的转折;③徐六注大、小潮表层絮凝体平均粒径在体积浓度75μl/L时出现平均粒径与体积浓度关系的转折,体积浓度小于75μl/L时粒径随体积浓度增加而增大,超过75μl/L时粒径随体积浓度的增加变化不明显;④絮凝体有效密度由粒径大小控制,粒径大,有效密度小,反之亦然,粒径和有效密度共同决定絮凝体静水沉速,有效密度和沉速与平均粒径之间均存在良好的幂指数关系。

The results showed that the grain yield of winter wheat with two-irrigation was higher than that with one-irrigation with the same nitrogen application rate and method. Compared to one-irrigation,the grain number per spike in two-irrigation was higher,the 1000-grain weight was lower, the water wastage was higher, but the WUE was lower. The yield was not affected significantly by nitrogen rates and the methods. Within the nitrogen rate of 157.5-295.5kg/hm2, the lower NUPE and Nitrogen Productivity declined with nitrogen rate increasing. NHI was not lower than the others at the lowest nitrogen rate of 157.5kg/hm2. The accumulation of NO3--N in soil was significantly and positively correlated with the nitrogen application rate. NO3--N in one-irrigation was distributed mainly in the top layer (0-80cm), but it was inverse in two-irrigation.
结果表明,施氮量和施氮方式相同时春浇二水冬小麦的产量高于春浇一水,二水穗粒数较一水高,千粒重则低于一水,一水耗水量较少,水分利用效率明显高于二水;同一水分下不同施肥量及施肥方式对产量的影响差异不显著,同一施肥方式下在157.5-295.5kg/hm2范围内,施肥量越大,氮素生理效率和氮肥生产力越低,施氮157.5kg/hm2时,氮收获指数均处在最高或较高水平;土壤硝态氮残留量与施氮量呈显著正相关,成熟期一水条件下土壤中硝态氮主要集中在上层(0~80cm),二水条件下则主要分布在中下层。
