The Mssbauer spectra show that the easy magnetization direction(EMD) of Tb_ 0.3 Dy_ 0.7 (Fe_ 1-x Al_x)_ 1.95 may deviate slightly from the major axis of symmetry <111> with the component and temperature,i.

From a test and analysis of a plasma arc which is under the re-constriction of dual-cusp magnetic field (DCMF) for its appearance, its electrical, mechnical and thermal characteristics, as well as its stability, it is found that using a DCMF re-constriction plasma arc and cutting along the major axis of its cross-section is able to effectively improve cut quality, process stability and cutting productivity.

The effects of the elliptic defect models of various ratioes of major axis to minor axis, the standard M-K defect model and the Circular delect mouels on the limit strains for a biaxially-stretched sheet are studied with large-strain FEM. large strain versions of J2 flow theory and J2 deformation theory of plasticity.

The results show that the effects of the elliptic defect on the limit strain for biaxially-stretched sheet metals are related to the ratio of major axis to minor axis of ellipse and the sheet thickness in elliptic region.

At the phase plane "the longitude of the subsatellite point-semi-major axis" the regions of migration of separatrices where the separatrices can move due to the influence of perturbations are isolated.

The dimensions of these regions and the distances between them have the same order of magnitude, several kilometers along the semi-major axis.

We found no evidence of gas rotation around the major axis of NGC 6286, which argues against the assumption that this galaxy has a forming polar ring.

We found no significant deviations from the circular rotation of the galactic disk in the velocity field in the regions of brightness excess along the major axis of the galaxy (the putative polar ring).

Using Green functions in an infinite medium, the constraint stress field of an inclusion with general shape is given. The stress free strains of the inclusion may be functions of position. On this basis, all calculating formulas for plane problems are given. We consider cracks or holes as special inhomogeneities with elastic constants equal to zero. For a body stressed by the applied field, the stress-free strains of the equivalent inclusion have been calculated. For oblate inclusions, near the end of major...

Using Green functions in an infinite medium, the constraint stress field of an inclusion with general shape is given. The stress free strains of the inclusion may be functions of position. On this basis, all calculating formulas for plane problems are given. We consider cracks or holes as special inhomogeneities with elastic constants equal to zero. For a body stressed by the applied field, the stress-free strains of the equivalent inclusion have been calculated. For oblate inclusions, near the end of major axis of ellipse, the stress field exhibits a r-(1/2) stress singularity similar to that of a crack. Some applications, including the interaction of a hole with the applied field, micro-crack nucleation due to martensite plates and deformation twins, are discussed.

A new technique of PAW is presented on the basis of investigation on the features of welding heat source and the mechanical condition of the molten pool, This new technique is characterized by using a dual-cusp magnetic field to make the plasma are flat and welding along the major axis of the cross section of are. The most valuable advantage of this method lies in the allowance of increasing the metal thickness for dual-sided formation by a single pass. This paper introduces the experimental results of...

A new technique of PAW is presented on the basis of investigation on the features of welding heat source and the mechanical condition of the molten pool, This new technique is characterized by using a dual-cusp magnetic field to make the plasma are flat and welding along the major axis of the cross section of are. The most valuable advantage of this method lies in the allowance of increasing the metal thickness for dual-sided formation by a single pass. This paper introduces the experimental results of welding 16mm thick stainless steel by this method under a real production condition. The technological characteristics of this technique and the pattern of the weld formation as well as the influencs of different parameters are discussed. Because the holing ability of plasma, by adopting this method, can be strengthened by increasing the field current, it is unnecessary to make a substantial increase of welding current for increased metal thickness. As a result, the sizes of the pool and the keyhole are restricted, So it is much easier to maintain the liquid metal in mechanical equilibrium
