It is concluded that, first, geochemical data of the surface soils can clearly distinguish two kind of soils, that is, juvenile soils, for example, purple soils, which inherits most geochemical characteristics of the parent rocks or materials, and anthropic soils, the geochemical characteristics of which have been greatly changed as the results of intensive impact from variety of agricultural uses. Second, different soils have typical indicator elements association respectively due to different parent rocks or materials and utilization, such as purple soils, yellow soils (low alkali and alkaline-earth metal contents and pH value), paddy soils (high organic element and heavy metal elements contents) and fluvo-aquic soils (high rock-forming accessory mineral elements contents) and so on. Consequently, it can be suggested that elements association is an important indicator for two key factors (parent materials and anthropic activities) of soil classification. Third, some differences exist between soil genesic classification and result of cluster analysis, because geochemical characteristics of surface soils can not completely represent the foundation applying to soil genesic classification, that is, condition and process of soil-forming, and soil property.

Luneberg lens is a spherical lens which its permittivity varies with normalized radial coordinates. It is fabricated by using different homogeneous dielectric centrically layered media. The lens can focus a parallel beam of rays from any direction exactly at a point on the surface. If it is made by adding a reflecting surface "metallic cap", it is called Luneberg lens reflector. It can reflect incident wave into plane wave in incoming direction. It is usually applied in antenna, radar reflector,satellite-based, and mobile-communucation.

龙伯球透镜为一种介电系数与半径成一固定比例的球形透镜，大部分是由数层不同介电系数介电质组合而成，而其主要特性能够把入射波聚焦到球表面一点，假使在透镜表面处镀上一圆锥角金属层即为龙伯球透镜反射器，能把入射波依平面波的型态反射回原入射端，通常用於天线、雷达、卫星通讯、军事等方面。

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.
