Result In the first 4 d of experiment, the corrected mortalities of spore suspensions with various concn. of P. cicadae APC20 to P. xylostella were lower than 50%, but on the 7 th day, that of spore suspension with concn. of 3.0×10^8 spores/ml reached 85.11% and the insect corpses was bestrewed in the mycelium and spore powder of P. cicadae, indicating that APC20 showed stronger parasitic lethality to P.

结果]药后第1~4天,蝉拟青霉APC20各个浓度的孢子悬浮液对小菜蛾的校正死亡率均低于50%,而第7天,浓度为3.0×10^8个/ml的孢子悬浮液对小菜蛾的校正死亡率达85.11%,并且虫尸布满蝉拟青霉的菌丝体和孢子粉,说明APC20对小菜蛾呈现较强的寄生致死性。

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。
