The obrained numerical results indicate that the EPR parameters are related tightly to the ground and excited states (ie, the spin-quarters and spin-doublets): The second rank parameter D comes mainly from the spin-quartets and negligibly from the spindoublets.
α-F进行了一般性研究,研究表明:EPR参量与其基态和激发态(自旋四重态和自旋二重态)有密切联系,且有如下规律:二阶参量D主要来自自旋四重态,自旋二重态贡献较之小得多;四阶参量α-F则主要来自二重态,四重态的贡献很微弱,但不能忽略。
This treatise advances planning, mechanism, qualified personnel, and four importance s, that interpret the four elements in the settlement.
而学科建设是一项庞大的系统工程,工作千头万绪,又该从何入手呢?文章提出学科建设的四要素:规划建设、机制建设、队伍建设、“四重”建设。
Middle REEs (MREE) enrichment and M-type tetrad effect were observed in roots, and precipitation of phosphate with REEs was suspected to be responsible for the phenomena, which should also cause W-type tetrad effect in shoots.
