As such , the representation of the deep overlapping of the wavepackets of valence electrons as well as of other nuclear events is beyond any credible hope of quantitative treatment via quantum mechanics or chemistry on conceptual , mathematical and physical grounds 这样,对原子价电子深深重叠的波包,以及其它核事件的描述,在概念、数学和物理基础上均超越了通过量子力学或化学进行量子处理的任何可靠的希望。
In the paper , the relationship between the wettability and the valence electron structure of ceramic multiphase in ti ( c , n ) based cermets was studied , which expects to present theoretical instruction for preparation of high performance cermets and enrich materials design theory 本文研究了ti ( c , n )基金属陶瓷中润湿性与陶瓷相价电子结构的关系,以期为制备高性能ti ( c , n )基金属陶瓷提供理论指导,丰富材料设计理沦。
South chengdu the valence electron electricity limited liabilitycompany mainly is the collection development production to a body , isengaged in the vacuum coating equipment the electronic surveyinginstrument and the electrical control development , the development , the production and the integration 成都南仪电子电气有限责任公司主要是集开发生产于一体,从事真空镀膜设备的电子测量仪器和电气控制的开发、研制、生产和集成。
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 最后根据eet理论计算了sr 、 mg掺杂的lagao _ 3材料中陶瓷相的价电子结构,结果表明,陶瓷相的n _ a和活化能是影响电导率的两个主要因素。我们可以通过陶瓷相的na和活化能来预测具有高电导率的材料成分。
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 最后通过eet理论计算了多元陶瓷相价电子结构,结果表明,添加不同碳化物均能导致n _ a增加,对价电子n _ a增加的效果由大到小依次为vc mo _ 2c nbc wc tac ;以价电子结构为桥梁,通过多元线性回归及多项式回归建立了成份与润湿性的关系。
