In a sense, the lag of management is a more serious problem than the lag of technology.

在某种意义上，管理落后是比技术落后更严重的问题。

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。

Do not confuse the above definitions of lead/lag in the spatial domain with the electrical definitions of lead/lag in the radian domain.

不要把上面定义的空间域的超前/滞后定义与电学定义的弧度域的超前/滞后混淆）。

In this study, sulfate radical concentration from 4 drip water points (PL1, PL2, SH, JG) in the Shihua cave have been monitored for three years, and those from the drip water point was monitored for two years. Drip discharges show three types of response to surface precipitation variations: rapid response, response with associated time-lag and stable. The results show that:(1) SO(superscript 2- subscript 4) concentration in rapid response drip water increases sharply during rain period and has a exponential relationship with drip rate;(2) in the drip water of lag response, SO(superscript 2- subscript 4) concentration has no significant incrcase during rainfall, but they show a increasing trend during a long-term monitoring;(3) SO(superscript 2- subscript 4) concentration at the stable drip site is low and has no obvious change during wet weason.

本文通过对石花洞洞穴4个滴水点（JG， SH， PL1和PL2）硫酸根浓度近3个水文年的分析测定，结果表明：响应降雨快的滴水点滴水SO(上标 2-下标 4)浓度升高幅度最明显，且滴水SO(上标 2-下标 4)浓度与滴率成指数关系；滞后响应降雨的观测点滴水SO(上标 2-下标 4)浓度雨季升高幅度不明显，但在长期观测期间有明显增加的趋势；对降雨没有响应的滴水点，其SO(上标 2-下标 4)浓度低且雨季没有明显变化。

The method made lead and lag errors boil down to GPS errors, which could be emendated by map data on the basis of the observability of GPS errors along the vertical direction. A general Kalman filtering was constructed to process the information of corrected GPS and DRS later, Which decreased lead and lag errors in the integrated navigation system.
