First, each shape is represented by the eigenvectors of an appropriately defined affinity matrix based on approximated geodesic distance, forming a spectral embedding which achieves normalization against rigid-body transformations, uniform scaling, and shape articulation (i.e., pose changing). This procedure is called the pose-oblivious transform.

The less-sheared regions caused by friction resistance are observed at lower and top parts, which are symmetric and gradually extend to the inner part along the sample longness. The less-sheared region percentage increases with ECAE processing.

The experimental results show that microwave sintering promotes the densification of green compacts with higher heating rate and reduced sintering cycle. The sintered relative density of 99.8% can be achieved during microwave processing under appropriate conditions. In addition, microwave sintering improves the uniformity and homogenization of W grain size, and yet leads to growth of W grain. Fe sintering aid degrades the microstructure uniformity and further coarsens W grains. The present investigation demonstrates the feasibility of applying microwave sintering technique to consolidate W-Cu composites and its promising outlook in reducing production cycle and cost.

For sample with longer GI time, which resulting in the better uniformity of this sample, the unusual decrease of FWHM is not observed in the measurement of the temperature dependent PL spectra. Considering the better uniformity of the sample, the effect of carrier redistribution on PL spectra is unapparent. Therefore, the FWHM increases gradually with temperature.

对於成长中断时间较长的样品来讲,由於其均匀度较佳,所以在变温的光激光谱量测中,我们并未发现半高宽随温度上升而有下降的趋势,这是因为载子重新分布效应对一个均匀度佳的样品来讲,其显示出来的效果并不明显,所以我们只能观察到电子与声子散射效应所表现出来的现象,也就是半高宽随温度上升而缓慢增加。
