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。

Since Al〓Ga〓In〓P possesses larger valence band difference to GaAs and wider energy gap, minor carrier reverse injection from base and space charge region recombination in the emitter are effectively suppressed in Al〓Ga〓 In〓P/GaAs HBT. Under most circumstances, quasi-neutral base recombination current dominates the base current, and its ratio to collector current varies little with collector current and temperature, thus greatly stabilizes the current gain.
Al〓Ga〓〓In〓P/GaAs HBT由于异质结的△Ev较大,发射区禁带较宽,有力地抑制了基区少子反向注入流和发射区空间电荷区复合电流;在大多数情况下,基极电流以准中性基区复合电流为主,其与集电极电流的比值随集电极电流和温度的变化极小,稳定了电流增益。
