The structural and magnetostrictive properties of (CexTb1-x)0.5Pr0.5Fe_2 were investigated. Ceconcentration must exceed x=0.6 in order to obtain the pure Laves phase. The magnetostriction and anisotropy constant increase with the Tb-content in this system. The anisotropy value of PrFe_2 is lower than that of isostructural DyFe_2. From the X-ray step-scanned data we found that λ_111 of PrFe_2 is 1310x10^-6. A large increase of magnetostriction can be observed under a small prestress of 6 MP_a for Ce_0.5Pr_0.5Fe_2.

用四端引线法测量了4.2K到室温的非晶态(Fe1-xCox)18Si9.5B12.5（x=0—1.0）合金的电阻率。结果表明,x=0—1.0的所有样品都出现了电阻率与温度关系的极小值。电阻率极小值温度Tmin随Co含量x的增加而增加,在x=0.9时出现极大值。在Tmin温度以下,电阻率与温度关系符合-lnT规律。x=0.5—1.0的样品,电阻率与-lnT关系出现两个斜率。在Tmin温度以上,约100K以下电阻率符合T2规律,在约100K以上电阻率则按T3/2规律变化。实验结果表明,约在9.5K和100K温区,电阻率与温度关系可近似表达为:ρ/ρmin=ρ0+AlnT+BT2。显现类Kondo型电阻极小。电阻率的T2关系来源于电子-声子散射。

Due to the poor filling effect of the video image defect commonly used in the video stabilization field, the video is seemed still unstable after the image stabilization process, which seriously affects the visual effect. To solve this problem, we improve a video stabilization method based on time-series network prediction and pyramid fusion restoration is proposed to optimize the visual effect after image *** flow of the proposed method is as follows: First,it is adaptive to determine whether the defect of the corresponding frame at the current time needs padding inpainting. Then, for the frame that needs to be inpainting,the frames generated before the current moment are sent to the model combining the convolutional neural networks and the gate recurrent unit to predict the part to be filled. Next the current defect image and the complete image to be filled are brought into the Laplacian pyramid reconstruction, and the improved weighted optimal suture is introduced for splicing during the fusion. Finally, the video frame is cut after reconstruction. The method is tested on a data set composed of videos commonly used in the field of video stabilization. The experimental results show that the average peak signal to noise ratio of the method is 2 to 5 d B higher than that of the comparison algorithm, and the average structural similarity index is improved by about 2% to 7% compared with the contrast algorithm.
