The association chain implied is general reactivity, delocalization, heat of reaction, activation energy, velocity constant . 和该量有牵连的因素是一般活性,离域作用,反应热,活化能,速度常数。
The template method is superior to other approaches , which the size , structure and morphology of the prepared materials can be controlled and adjusted by simple altering the nature of the template and the preparation conditions 模板法的优势在于利用模板的空间限域作用和调控作用可对合成材料的大小、形貌、结构、排布方式等进行控制,而且也可根据合成材料的大小和形貌预先设计模板。
