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.

A Theoretical Approach for Estimating Fracture Toughness of Ductile Metals

Fracture toughness is very important when applying Damage Tolerance Design and Assessment Techniques. The traditional testing approach for obtaining fracture toughness values is costly and time consuming. In order to estimate the fracture toughness of ductile metals, the fracture mechanics theory, materials plastic deformation theory and materials constructive relationships are employed here. A series of formulae and a theoretical approach are presented to calculate fracture toughness values of different materials in the plane stress and plane strain conditions. Compared with test results, evaluated values have a good agreement.     

Research and Application of All-Position Automatic Welding Machine

The all-position automatic welding machine system is the special welding system for pipeline girth automatic welding on site, which has been widely used in the long distance pipeline construction projects due to the advantages of automatic control for welding parameters at all position, moving speed of bugs and operating. This automatic pipeline welding system has been successfully used in several main pipeline projects in China, and has been approved by the constructors with the benefits of higher quality passing rate, higher welding efficiency and lower labor intensity.
