Nuclear Technique and Agriculture in China

Nuclear technique is a powerful scientific tool in agricultural research, an area with fruitful achievements in China. Application of nuclear technique in agriculture (Nuclear Agricultural Sciences) based on the development of related science and technology is a high-tech area, and also a significant aspect of non-electrical power application of nuclear technique. As an important component of agricultural science and technology, Nuclear technique application in agricultural field has achieved a lot and made remarkable contributions to the economic, social and ecological development of China. The current paper reviews the achievements, and presents the situation of the application of nuclear technique in the Chinese a-griculture briefly. The author strongly suggests that Chinese     

Research Frontiers of Agricultural Economics and Management

The focus of research on Agricultural Economics and Management (AEM) has been switching from de-veloped countries to developing countries. In important international journals on AEM such as ““American Jour-nal of Agricultural Economics““ and ““Agricultural Eco-nomics““, the research objectives mainly focus on AEM problems in developing countries, e.g. the effects ofglobalization and liberalization on agricultural produc-tion in developing countries, and problems in agricul-tural resources and environmental protections in devel-oping countries.     

Fabrication and Properties of CoSm-Based Multilayer Thin Films

In recent years, SmCo series thin films have been found to be good candidates for fabricating integrated electromagnetic components and ultrahigh density magnetic recording media[1,2]. Up to now,intensive studies of such films have been carried out in order to obtain appropriate microstructure, crystallographic orientation and other properties. Substitution of Cu or Ni for Co in SmCo/Cr series films leads to a decrease of the saturation magnetization, magnetic switching volume, and to an increase of uniaxial anisotropy and coercivity[3-5].Various deposition conditions have also been investigated[6]. The large increase in coercivity for the annealed SmCo/Cr films is due to the growth of crystallitest[7,8]. In this article, we report a study of the deposition process,structure, and magnetic behavior of sputtered Sm (Co,Cu, Ti)/Cr series thin films.
