近年来,不同体系的高熵陶瓷迅猛发展,但萤石结构高熵氧化物仍处于研发初期。本研究采用机械球磨和常压烧结的方法合成一种新型高熵萤石氧化物,利用XRD,SEM,TG-DSC和可视化形变分析仪研究了陶瓷的物相转变、表面形貌以及烧结行为。研究结果表明,(Zr_(1/7)Hf_(1/7)Ce_(1/7)Y2/7La_(2/7))O2-δ是一种非等摩尔的“高熵”陶瓷,其内部各元素分布均匀。湿法球磨和干法球磨制备的粉末结构和粒度均有所不同,单相转变温度为1600和1300℃,圆盘状坯体在1600℃保温1 h,尺寸收缩率约为8.5%和17.8%,致密度分别为82.25%和93.23%,说明球磨工艺是影响高熵陶瓷烧结的重要因素。此外,常压烧结制备(Zr_(1/7)Hf_(1/7)Ce_(1/7)Y2/7La_(2/7))O2-δ时,在1300~1600℃应适当减缓升温速率并延长保温时间,避免生坯收缩开裂,并提高陶瓷致密度。

作为度量粒化程度的方式,在粒计算研究领域中,粒度受到了众多学者的广泛关注,其中一种重要且广为接受的模式是参数化粒度。利用这种参数化的粒度表现形式,在面向属性约简的求解问题时,往往需要计算每一个参数所对应的粒度下约简,直至找出所有参数下的约简结果。显然,这种方式会带来巨大的时间消耗。为解决这一问题,提出了一种连续参数意义下的多粒度属性约简策略:首先利用连续参数的区间及粗糙集中不确定性度量的单调性,构造了连续参数下属性约简的约束条件;其次设计了连续参数意义下约简求解的前向贪心搜索算法;最后选取了8组UCI数据集进行实验对比分析,结果表明,相较于多个离散参数下的单粒度属性约简,连续参数意义下的属性约简可以在使得约简中属性的分类性能不发生显著变化的情况下,极大地提升约简求解的时间性能。这一研究为从连续视角进行多粒度建模及相关属性选择工作提供了新的解决方案。

强连通分量问题的实质是将有向图分解为一组互不相交的极大强连通子图.每个子图中的任一顶点到其它顶点都是可达的,既是其它顶点的祖先,又是后代.利用宽度优先搜索(BFS)可得到目标有向图中任一顶点的祖先顶点集与后代顶点集,两个集合的交集即为包含当前顶点的强连通分量.首先,基于BFS的强连通分量挖掘方法(BSCC)的效率取决于BFS被调用次数,因此,引入了3种启发式信息来减少BFS调用次数.对强连通分量进行深入分析,发现了顶点间的两种相关性.满足任一相关性的两个顶点不会分属两个有价值强连通分量.根据这两种相关性提出了一种顶点粒化策略,可构建每个顶点所对应的顶点粒,继而提出了基于顶点粒的强连通分量挖掘算法(GSCC),优化了BSCC算法中顶点调用BFS的方式,提高了强连通分量挖掘效率.实验结果表明,相比BSCC算法和线性复杂度的Tarjan算法,GSCC算法具有更好的性能.
