On average, the SSC in winter is 2 times than that in summer; and the SSC in spring tide is 2.96 times than that in neap tide.(2) The correlation coefficient of the daily tidal range and SSC at a tide circle is 0.86, and it goes up to 0.96 and 0.93 with one day and two days lag of SSC. This reflects that there has a hysteresis of one or two days of SSC to the tidal range.

三年平均而言，冬季悬沙浓度为夏季的2.0倍，大潮悬沙浓度为小潮的2.8倍；(2)平均的大-小潮半月周期变化中日悬沙浓度与同日潮差之间的相关系数为0.86，(显著性水平0.01)，与提前1日潮差之间的相关系数为0.99(显著性水平0.01)，与提前2日潮差之间的相关系数为0.93(显著性水平0.01)，反映潮差变化对悬沙浓度的影响有1-2天的滞后效应；(3)芦潮港月均悬沙浓度与长江大通站的月均流量呈显著负相关，尤以流量滞后19天的相关性最好。

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。

In this model, the skeletal storage coefficient was used for coupling, different storage coefficient were used for the calculation of storage change of aquifer and interbeds, the elastic and inelastic skeletal coefficients were used to account for the elastic and inelastic deformation, a one-dimensional diffusion equation was used for describing the delayed dissipation of unequilibrated heads within the interbeds, these make the model not only be able to simulate the elastic and inelastic deformation of soil, but also the delay phenomenon.

在该模型中，用夹层的骨架弹性储水系数进行地下水流模型和土体变形模型的耦合，用不同的弹性储水系数来计算夹层和含水层内的储水量变化，用夹层的骨架弹性储水系数和非弹性储水系数来体现夹层的弹性和非弹性变形，用扩散方程来描述滞后夹层内的水头分布，从而使模型能够很好地体现夹层的弹性和非弹性压缩，并能同时考虑夹层变形的滞后现象。

As to the mate lag problems in loom beat up mechanism,comparing traditional four bar linkages with quick return four bar linkages beat up mechanism,the latter can solve the lag problems effectively.A CAD method of designing the quickreturn four bar linkages beat up mechanism is pointed out,and the design mathematics model and the kinematic analysis model are also presented.

The main conclusions and outcomes are as follows:(1) From the coupling mechanism of economy and environment, the author appraises the degree of sustainable development in Jinlin province. The results show that the development orientation of Changchun is prone to economic development, for Jilin it is environmental development and for Liaoyuan it is harmoniums development at low level. By quantitative analysis, the author studies the status of sustainable utilization of water resources in this region from three aspects: water supply, drainage and water quality, and the results show that utilization of water resources in each of nine areas that belongs to Jilin province is at low level.
