A new kind of in-situ ceramic consolidation molding process was investigated on the basis of the characteristics of starch swelling in water and gelatinizing when heated. The SiC ceramic suspension containing about 50vol% solids loading and about 3wt% starch can be cast and molded into various complex-shape SiC ceramic parts in a water-thermostat. The dry shrinkage of the green body was less than 1.0% when the solid volume fraction of SiC suspension was up to 52.5%. The density and pore size were homogeneously distributed inside the biscuits. Soaked with melt silicon in a vacuum arc face, the biscuits were t into SiC ceramic materials with homogeneous structure and high performances.

提出了一种最小化光谱相关度约束的非负矩阵分解方法。该方法根据高光谱遥感图像中端元之间具有不相关性这一特点,提出了一种光谱相关度函数。该函数度量光谱之间的相关程度,函数值越小,光谱间的相关度越小。通过联合最小化光谱相关度函数和非负矩阵分解误差函数,使获得的光谱之间具有最小的相关性,从而获得端元光谱以及组分图。模拟实验和真实实验证明了算法的有效性。
