By means of analytical and numerical calculations,the spin reorientationtransitions in sublattice magnets(including one-sublattice and two-sublattice magnets)and the spin configurations in magnetic films have been systematically studied.

本文借助于解析求解和数值计算的方法，系统地研究了亚点阵磁体(包括单亚点阵和双亚点阵磁体)中的自旋再取向转变和磁性薄膜系统中的自旋组态。

It is discovered that there is a new magnetic transition: the first order spin reorientation reform , at which the magnetization, the anisotropy coefficients and the mean fields of the two - sublattice system change, accompanying with the spin reorientation.

The introduction of torsion field can be included in a new meaning to the concept of physical vacuum . All kinds of fields (electromagnetic field, gravitational field and torsion field) can be regarded as the behaviors of physical vacuum under different polarized conditions. If one charged particle in vacuum spins to lead to the charge polarization of the vacuum , it takes the form of electric field ; if the move source is mass, by which the spin leads vacuum to the vertical polarization, it takes the form of gravitational field; If the spin is self-spinning to lead vacuum to the horizontal polarization, it takes the form of torsion field.

挠场的引入从最基本的层次上可以纳入对物理真空这一概念的新的理解上；各种场都可以看作为物理真空在不同极化条件下的表现；如果一个带电粒子存在于真空，作为一种挠动，使物理真空被电荷极化，就表现为电场；如果这种挠动源是质量，物理真空在质量的挠动下引起真空的自旋纵向极化，就表现为引力场；如果这种挠动是由于物体的自旋引起的，那么，真空被横向极化，就表现为挠场。

Results:(1) Spin-echo sequence included axial, coronal and sagittal images. In T1-weighted images,the medulla oblongata is isointense,the cistern is hypointense; in T2-weighted images,the medulla oblongata is isointense, CSF shows hyperintense, and the arteries of posterior fossa appear hypointense flow voids. The cisternal cranial nerves are not clearly demonstrated in the routine spin-echo images. In 3D-time of flight images, the brain tissue shows isointense, CSF is hypointense, the artery shows hyperintense,and the cranial nerves show linear isointense.
