Then,firstly,the images were processed,and the phase compositions(relative contents of pores,matrix,alumina- zirconia eutectoid and primary baddeleyite) of the samples were obtained by counting. Secondly,the correlation coefficients of all parameters were calculated; indistinctive coefficients and unimportant variables were eliminated by F- test. Thirdly,the roadmap of the parameters was established and explained according to professiona knowledge.展开更多
