In the investigation of Cu-Zn-Al SMA, the influence of quenching speed, shape memory thermal treatment on SME, microstructure and morphologies was discussed. The changes in morphology and interfaces were in situ metallographic observed during thermal cyclings in order to control the degradation of two way shape memory effect . The stabilization of stress induced martensite variants method and the accordingly changes in microstructure were studied in detail. The mechanism was also compared between SSIM and TWME training method. From the above in situ observation results, the interface structure and especially the twin related A: B type variant pair were examined by HREM to clarify the role of movability of interfaces and the changes in variants orientation in inducing the degradation of the TWME. During developing the Ni-Ti-Hf SMA melt spinning ribbon, it was found the morphology and structure embodied the SME and was directly effected by chemical composition and technique factors, such as the different content of Hf, the speed of copper roller rotation and etc. Therefore, the morphology and structure were extensively examined.

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 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。
