Analysis on the spin reorientation of GdFeCo/DyFeCo exchange-coupled double-layer films

In this paper, GdFeCo/DyFeCo exchange-coupled double-layer films used for center aperture type magnetically induced super resolution were investigated through experiments and theoretical calculation. The samples were prepared by magnetron sputtering method. The polar Kerr effect was measured to prove the spin reorientation of the readout layer. Theoretical study of magnetization profiles was performed on the basis of the mean-field theory and the continuum model. The theoretical results showed that the magnetization orientation of the readout layer changed gradually from in-plane to out-of-plane with the rise of the temperature. Theoretical analysis explained the experimental results successfully. (c) 2005 Elsevier B.V. All rights reserved.

空间碎片的激光雷达探测

为了利用激光雷达对空间碎片进行探测,根据空间环境和空间碎片的特性,给出了空间中的激光雷达作用距离的具体表现形式,并详细分析了空间的背景辐射并给出了处理后的结果,从而推导出最小可探测光功率的计算公式,进而给出了系统所需最小发射光功率和探测系统的信噪比。结果表明,利用激光雷达可以对几十千米范围内的较大空间碎片进行探测。

板料激光斜冲击下受力变形数学分析

金属板材的激光冲击成形通常采用激光束垂直作用于工件表面，产生垂直于表面的冲击波作用力使板料变形，但在曲面零件成形时很难满足法向垂直冲击。因此有必要对斜冲击下板料力学变形特性进行研究。本文研究了激光斜冲击受力变形模型，对板料深度方向（Z轴）变形公式、板料短轴（y轴）在水平方向上变形公式进行了理论推导计算，通过把两变形合成，得到短轴（y轴）在空间内总变形公式，最后把实验测量结果与理论计算结果进行了比较，得出两者相符的结论。
