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.

悬沙浓度具有显著的大、小潮和季节性变化，变化周期分别为14.7 d和368 d，平均而言，大潮为小潮的2.96倍，冬季为夏季的2倍；2）平均大、小潮半月周期中日悬沙浓度与同日潮差之间的相关系数为0.86，与前1日潮差之间的相关系数为0.99，与前2日潮差之间的相关系数为0.93，反映潮差变化对悬沙浓度的影响有1~2d的滞后效应；3）月均悬沙浓度与长江大通站的月均流量呈显著负相关，尤其与流量滞后19d的相关性最好。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
