The experimental results show that the content of SiC in RBSC increases with carbon content while α-SiC is chosen as a filler. However, the residual carbon would appear in specimens when the carbon content exceeds 30% by weight. Using carbon felt, the reaction-formed SiC particles are small and uniform in size and distribution. However, when carbon felt is impregnated with phenol resin, the reaction-formed SiC is nonuniform in size and distribution. X-ray diffraction shows that the fabricated RBSC is composed of α-SiC,β-SiC, and free Si. The polytype of SiC is related to the reaction-heat during sintering.
结果表明:选用α-SiC+C粉的混合物作为生坯,SiC相的体积分数随生坯中wC的增加而增加,但过大的wC将使硅化后的试样出现残碳;选用碳毡作为生坯,反应烧结碳化硅的显微组织特点是C/Si反应生成的碳化硅颗粒均匀细小,并呈线状分布在游离硅中;浸渍过树脂的碳毡硅化处理后的显微组织特点是反应生成的碳化硅颗粒粗大且呈不均匀分布。X射线衍射结果也表明,反应烧结碳化硅陶瓷由游离Si、α-SiC、β-SiC组成,试样中不同晶型碳化硅的出现与C/Si反应的放热过程有关。

The method includes the following steps: firstly, a spherical neighborhood of present sample points is established by using the geometric spherical-modelling theory and all the sample points contained in the spherical neighborhood are adopted as candidate neighbor points, thus not only preserving the effectivity of the dimension reduction capability when data sets are sparse but also getting the advantages of low-sensitivity to isolated points and good stability of the preserved topological structure; then a data relevance matrix more matching semantics can be obtained by relevance measurement based on route clusters to update the candidate neighbor points in the spherical neighborhood and optimize the regular neighborhood space of the present sample points, thus improving the phenomenon that the dimension reduction of sample sets provided with folded curved faces is apt to suffer the integrated-structure distortion in case of heterogeneous data distribution.
首先利用几何开球原理建立当前样本点的球状邻域,将包含在球状邻域内的所有样本点作为候选近邻点,不但能够保持在数据集稀疏情况下的降维性能的有效性,而且具有对孤立点敏感性不高、保留拓扑结构稳定性好的优点。然后利用基于路径聚类的相关性度量得到更符合语义的数据相关性矩阵,用来对球状邻域内的候选近邻点进行更新,优化当前样本点的规则邻域空间,改善了当数据不均匀分布时在带有折叠弯曲面的样本集上降维容易出现整体结构扭曲的现象。
