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。

The union of any two sets consists of those elements that are in one or the other or in both given sets; the intersection of two sets consists of those elements that are in both given sets.

任何两个集合的并集包含了出现于这两个子集中某一个集合或同时出现于这两个集合中的所有元素；两个集合的交集包含了同时出现于这两个集合中的元素。

The union operation is practically equivalent to the OR of sets. The union of two sets is another set where each element is a member of at least one of the sets, i.e., a member of one set or the other.

联合操作和集合的OR(或inclusive disjunction)其实是等价的，两个集合的联合是一个新集合，该集合中的每个元素都至少是那两个集合中的一个成员，即，属于两个集合之一的成员。

A simple way of saving the memory space is using the 256 ASCII codesby functions such as ACHAR(I and IACHAR in Fortran Compiler to represent 28 egg patterns (or less than 256 patterns). For examples: 00000000 to 11111111 has 256 egg patterns for yes/no data of eight days; 00000 to 22222 (system of no egg, one egg and two eggs) has 35 patterns for egg production of five days; and 0000 to 3333 has 44 patterns for system of no egg, one egg, two eggs and abnormal eggs in four days…etc.
