Thirdly , the valence electron structure of ceramic multiphase in ti ( c , n ) based cermets were calculated by eet theory , the results showed that na increased with additions of carbides , the order was vc > mo2c > nbc > wc > tac . based on the valence electron structure , the relationship between composition and wettability was set up through multiple linear and polynomial regressions 最后通過eet理論計算了多元陶瓷相價電子結構,結果表明,添加不同碳化物均能導致n _ a增加,對價電子n _ a增加的效果由大到小依次為vc mo _ 2c nbc wc tac ;以價電子結構為橋梁,通過多元線性回歸及多項式回歸建立了成份與潤濕性的關系。

At last , the valence electron structure of ceramic phase in strontium - and magnesium - doped lagao3 were calculated by eet theory , the results showed that the electrical conductivity is determined by the na and the activation energy of the ceramic phase , we can forecast the ceramic optimizing composition with higher electrical conductivity by studying the na and activation energy of the ceramic phase 最后根據eet理論計算了sr 、 mg摻雜的lagao _ 3材料中陶瓷相的價電子結構,結果表明,陶瓷相的n _ a和活化能是影響電導率的兩個主要因素。我們可以通過陶瓷相的na和活化能來預測具有高電導率的材料成分。
