研究了颗粒含量对自生MgO／Mg2Si颗粒增强Mg—11Li基复合材料凝固组织的影响，得出了颗粒技界面俘获或推移的热力学条件及颗粒推移距离表达式随颗粒含量和凝固速度增加以及推移临界速度的减小。
The conception of earth mover s distance (EMD) is introduced, which can weigh comparability between two images, then a method is constructed to match image based on EMD.
对一种衡量图像之间相似性的推土机距离EMD度量做了介绍,提出了一种基于EMD度量的图像匹配方法。
