The sand dunes analyses data have shown they mainly consist of well sorted, symmetry skewness and find sands, and the kurtosis peak is narrow or very narrow. There are abundant impacts of mechanic process on the surface of quartz grains. The traces of eolian process often superpose on the traces stamped by river and beach processes. The dish--shaped concavities and mechanic pits are the most common surface textures, but the barchan concavities and curved grain edges are indicated the marks by eolian environment. The heavy minerals assemblages of coastal dunes are dominated by relatively high specific gravity which have stable chemical properity suggesting the mordern high dynamic environments of coast area. The depositional structures of coastal dunes are typified by corss--bed sets composed of steep foreset laminates and gentle windward dipping sets. It also contains some shell fragments and strong worn foraminiferal tests that are impossibly found in inland desert. On the other hand, the sandy deposits of the continental shelf of East China Sea are with wide range of grains, and the depositional pattens are quite complicated.

It is widely employed in many industrial domains. The most attractive domain of ring rolling technology is to roll the rings with specially-shaped cross section directly. But the rolling deformation law of ring with specially-shaped cross section is more complicated compared with rectangle section ring and in the process there are lots of special phenomenon such as underfilling, shrinking-drawing, concave, saucer shape and etc.

We have observed the structure of these dune sands and analyzed the grain-size,surface textural features and several main chemical elements of them,the results showed that:(1) these dune sands have some eolian structure characteristics which are similar to the recent dune sands;(2) they are also similar to the recent dune sands in grain-size components,and parameters of Mz,?滓,Sk and Kg,as well as in several main chemical components;(3) the scatter plots of Mz-?滓,SiO2-Al2O3+TOFE and the probability curves of grain-size showed that these paleo dune sands are different from paleosols and fluvio-lacustrine facies but are consistency with recent dune sands;and(4) the quartz sands have well roundness and some surface textural features such as dish-shape pits,crescent-shape pits,pockmarked pits,upturned cleavage plates,siliceous precipitates and siliceous crevasses,indicating that they had been carried for a long time by the wind.

Be practical and innovative, our team group work hard to complete the contents of the National Natural Science Foundation Project:"Study of the hydrodynamic behaviors of deep water sea cages". According to the development of the sea cage industry in domestic, two main widely concerning topics were added to our research program. They are the study of Sea station and Quasi-sea station cages. The workload and working strength increased dominately in our research. Delightful results were achieved with 26 science papers been proposed, in which 16 papers have been published or accepted by all kinds of journals or conferences.
