  yield regions
The result shows that the length of the plastic yield regions is not much affected by bonding, though its effect on the relative displacement between the lips of the yield regions is remarkable.
      
While degrees of relative homogeneity are apparent at many scales, the map was designed at a scale that would yield regions with sufficient homogeneity to be useful for lake management throughout the area.
      
Further it may be applied to other mechanical behaviour such as creep in the yield and post-yield regions and also the second order transition temperature that has been observed in stretched wool fibres in water.
      
This rising inequality can also be found where earlier low-yield regions are catching up because of improved technology.
      
Other high water yield regions are coastal Louisiana and Alabama and the Ouachita Mountains.

Based on both the calculating formula for J-integral determined by means of TPB type specimen and the experimental evidence of da/dN=C_1(ΔJ)~r ,an expression of subcritical fatigue crack growth rate characterized by AJ from TPB specimen from the linear elastic to complete yielding region has been derived as follows: For high-cycle fatigue crack, its approximate growth rate will be which seems to be identical with the Paris' relation. For high-stain fatigue crack, it may be which is analogous to the Coffin-Manson's...

The purpose of this paper is to improve some of techniques in designing a piston cylinder, ultra-high pressure vessel.First it introduces the elastoplastic analysis of the twofold cylinder which has been autofretted after shrink on and presents the formulae of autofrettage pressure and its cha- racteristic values. Then it derives the formulae of stress distribution in different regions and the formulae of displacements and strains in the yield region. In addition it proposes the approximate calculation methods of fracture analyses.Based on the results, the strength and fracture analyses have been made for the vessel. In analysing, two cases have been considered: autofrettage after shrink on and shrink on after autofrettage. Adopted are: 1) the material used is perfectly elastoplastic and 2) the axial stress is independent of the coordinate, r.

Having been analysed the present situation about the grain production and supply as well as the major factors influencing the steady increase of grain production in Sichuan, the responding countermeasures are proposed in this paper. In the near future, must give more effective leadership to the grain production, stabilize the planting area of grain crops, build the bases of commodity grain better and make grain yields in the middle and low-yield regions increasing much more, increase the input into agriculture,...

Having been analysed the present situation about the grain production and supply as well as the major factors influencing the steady increase of grain production in Sichuan, the responding countermeasures are proposed in this paper. In the near future, must give more effective leadership to the grain production, stabilize the planting area of grain crops, build the bases of commodity grain better and make grain yields in the middle and low-yield regions increasing much more, increase the input into agriculture, perfect the systems for popularizing agricultural techniques, strenghthen the scientific research of grain, perfect the system of purchasing grain according to contract. From a long-term point of view, should take three countermeasures, that are establising a reasonable price system in rural economy, gradually forming a scale of moderate degree in grain production and strenghthening the agricultural scientific research strate-gically.

分析了我省当前粮食的生产、供应形势以及影响我省粮食连续八年增产又出现徘徊局面的主要因素,提出了相应的对策。即在近期内应加强对粮食生产的领导,稳定粮食的播种面积,抓好商品粮基地建设和中低产区的增产,增加农业投入,健全农业技术推广体系,加强粮食科学研究,完善合同定购制度。从长期看,应建立合理的价格体系,逐步形成粮食生产的适度规模和从战略上加强农业科学研究。
