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.     

兽药添加剂喹乙醇对水生生物的毒理学研究

兽药添加剂喹乙醇是一种在畜禽及水产养殖中应用广泛的促生长剂 ,但其安全性仍存在较大争议 ,使用不当或过量使用会对环境构成潜在危害 .采用斑马鱼和鲤鱼作为生物材料 ,分别研究了兽药添加剂喹乙醇对斑马鱼的急性毒性、对斑马鱼胚胎发育的影响及对鲤鱼肾细胞DNA的损伤 .急性毒性试验表明 ,96hrLC50 为 1 996.87mg/L ;胚胎发育试验实验结果表明 ,96hrEC50 为2 2 1 .2 0mg/L ;单细胞凝胶电泳试验结果表明 ,喹乙醇能引起较大的DNA损伤 ,与空白对照相比有极显著性差异 (P <0 .0 1) ,并在设定的剂量范围内呈现一定的剂量效应关系     

三车道元胞自动机交通流模型研究

在Nagel-Schrekenberg（NS）元胞自动机交通流模型的基础上，提出了一种高速公路三车道元胞自动机交通流模型．该模型中所有的车辆均遵循相同的演化规则，并允许车辆以一定概率换道．根据计算机数值模拟．研究了车辆减速概率、换道概率对车流量、车道利用率影响关系，结果表明，在相同情况下，此模型所得到的基本图显示出交通流量比单车道NS模型大，并且发现减少不必要的车辆换道行为可以使驾驶更安全．这些研究为管理三车道的道路系统提供了一定的参考依据．     

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.     

P-RC APMP PULPING OF THE TRIPLOID OF POPULUS TOMENTOSA

The technology parameters of P-RC APMP process of the triploid of populus tomentosa and the the comparison of P-RC APMP with one and two stage f pretreatment were investigated in this paper. The results showed that in the chemical pretreatment the s that affected the pulp qualities. The charge of NaOH,y in the first stage of chemical pretreatment,was related to pulp strength. The charge of H2O2 tant pulp.In addition, the ratio of NaOH to H2O2 and the on of chemicals in the first and second stage of impregnation also affected the pulp qualities. The and two-stage P-RC APMP pulp illustrated that the ulp had better brightness and breaking length, lower light scatting coefficient and opacity.
