It is shown from the study results that (1) SSC has obvious neap-spring and seasonal variations with periods being 14.7 days and 368 days, respectively, on an average, SSC during the spring tide was 2.96 times as much as that during the neap tide, and SSC in winter was twice as much as that in summer;(2) correlation coefficient between daily SSC and tidal range on the same day in a mean neap-spring period of 15 days was 0.86, and correlation coefficients between tidal range and daily SSC with one day and two day lag were 0.99 and 0.93, respectively, which indicates that the effect of tidal range variation on SSC has a one day or two day hysteresis;(3) the monthly mean SSC was negatively correlated with the monthly mean water discharge at the Changjiang River Datong station, especially well with the water discharge with a lag of 19 days.

The temporal change in floes size of fine suspended sediments was measured in Xuliujin of the Changjiang Estuary in June of 2003, by using an in situ laser diffraction particle sizer, the laser in situ scattering and transmissomerty-100(LISST-100). The spectrum analysis was applied to analyze the fluctuation of floes diameter during the spring tide and the neap tide.

The observation showes that average VC, D,Δp and ω at the surface water during spring tide are 98.0μl/L, 39.8μm, 1173 kg/m^3 and 1.14 mm/s, whereas those during neap tide are 70.8 μl/L, 64.4μm, 919 kg/m^3 and 2.32 mm/s, respectively.

观测结果显示，徐六泾大、小潮表层絮凝体体积浓度、粒径、有效密度和静水沉速的平均值分别为98.0μl/L、39.8μm、1173kg/平方公尺、1.14mm/s和70.8μl/L、64.4μm、919kg/平方公尺，2.32mm/s。

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。

In the astronomy aspect, in 1672 Newton has formulated the reflecting telescope; He also explained not only the tide phenomenon, points out the tide the size the same lunar month related, moreover also has the relations with sun's attraction; Moreover, Newton extrapolated theoretically Earth is not a spheroid, but is the two-pole is slightly flat, the equator slightly drum, and explained the year old bad phenomenon from this and so on.

在天文学方面，1672年牛顿创制了反射望远镜；他还解释了潮汐的现象，指出潮汐的大小不但同朔望月有关，而且与太阳的引力也有关系；另外，牛顿从理论上推测出地球不是球体，而是两极稍扁、赤道略鼓，并由此说明了岁差现象等。

And after the nadir of the winter solstice the new sun secretly climbs towards the eastern horizon while the tide ebbs further and further out to final emptiness, whereupon Sol's nascent progression is suddenly announced at the vernal equinox, when he appears so resplendently above the distant waves and enters the upper vessel of day, which heralds the turn of tide, the reversal of regression to forward flow.

在冬至点之后，新日隐秘的上升至东方的地平线，潮汐一步步降落至最低处，直至初生的太阳最终到达春分点，在遥远的浪潮之上开始闪耀，进入一日的上半部分。这也预示了潮汐重新上涨，与之前的退潮相反开始顺流上涨活动。
