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.

海岸沙丘是晚全新世以来相对稳定的海平面背景下的海岸带风成堆积，其沉积特征是以细沙为主，分选好，搬运方式以跃移占绝对优势，偏度上近对称，峰态窄到很窄；石英颗粒表面机械作用形态丰富，风成作用形态叠加于河流和海滩过程形态之上，碟形坑和撞击麻点是最为常见的表面形态，而新月形坑和曲脊是其指示性的特征标志；沙丘沙重矿物以化学性质稳定、比重较大的种类为主，反映了海岸带目前的高能动力环境；海岸沙丘沙的沉积构造以高角度前积层和低角度顶积层组成的交错层理为典型特征，同时还含有少量内陆沙漠所没有的少量贝壳碎屑和强烈磨损的有孔虫壳体。

Environmental chemistry is an intersectant subject by environmental science and chemistry. Its core problem is to study the chemical transformation and effect of chemical pollutant in environment. The research object of environmental chemistry is a complicated system with many components and mediums. The content of chemical pollutants researched by environmental chemistry is very low. These chemical pollutants distribute extensively, move and transform quickly, and have obvious dynamic change under different space-time conditions.

环境化学是环境科学与化学的交叉学科，它的核心问题是研究化学污染物在环境中化学转化和效应；环境化学研究的对象是一个多组分、多介质的复杂体系；环境化学所研究的化学污染物在环境中的含量很低；化学污染物分布广泛，迁移转化速度较快，在不同时空条件下有明显的动态变化。

It is complicated to take, slow to take effect, and moreover, many of its components are irreproducible plants or animals.

For very long time, many research groups focus on using more than a stoichiometric amount of a chiral auxiliaries to obtain high enantioselectivity. There were mainly two sorts of processes reported on highly catalytic asymmetric addition of Grignard reagents to aldehydes. The former case was to transform Grignard reagent RMgX into other organometal reagents such as R_2Zn and R-Ti derivatives via complicated procedures at extremely low temperature. The later case was to link a chiral ligand to Mg in the form of organomagnesium amides or use chiral amine ligand catalyzing the alkylation of aldehydes.

格氏试剂对醛的不对称加成的报道大多需要大量的手性助剂以获得高的光学活性，而高度催化的格氏试剂对醛的不对称加成主要通过两种途径进行：一种是把格氏试剂转化成其他的有机金属试剂如R_2Zn和R-Ti化合物再对醛进行加成，反应通常在低温下进行；另一种是利用手性镁胺作为中间体或直接用手性胺催化来完成此反应。
