The framework established was practical and universal, and could provide abase for specific area to select its assessment indicators. The operable indicatorsystem developed which synthetically reflected the sustainable development status ofliling could fill up the blank of regional sustainable development evaluation in liling,and this work was of practical and strategic significance to a certain extent. Inallusion to the flaw existed indimensionlessness of original data in grey system,mean value method was adopted instead of traditional standardized method, and theguidance for confirming the direction of eigenvector was first brought to grey systemin the application of sustainable development evaluation aimed to increase theobjectivity and accuracy of evaluation. The evaluation results on liling could supplybeneficial references for decision makers to make and adjust sustainabledevelopment strategic goal and counter measures.

本文所构建的区域可持续发展指标体系框架具有实用性和通用性，可作为特定区域在筛选具体评价指标时的参考依据；针对醴陵市建立的区域可持续发展指标体系易于操作，能够综合反映醴陵市可持续发展的各个方面，在很大程度上填补了区域可持续发展评价研究的空白，具有一定的实践意义和战略意义；应用主成分分析法评价各子系统的可持续发展水平时，针对原始数据处理存在的弊端，提出以均值法代替传统的标准法，并首次引入了特征向量确定的原则，从理论上可提高评价的客观性与准确性；对醴陵市区域可持续发展状况的评价结果，可以为醴陵市可持续发展总体战略目标及相关措施的制定与结构调整提供有益参考。

不管是理论上还是应用上，凡是真正想经由期货交易赚大钱的人，都必须彻底了解这个简单的观念。

The bonding energy of the mixed covalent/metallic Ti-Al bond for the Ti-terminated Al/TiB_2 interface is larger than that of the polar covalent Al-B bond with partial ionic-like feature for the B-terminated interface. Metallic bond between Al atoms forms across the Al/AlB_2 interface, which results in weaker interfacial adhesion than that for the Al/TiB_2 interface. The interfacial energy for Al/TiB_2 depends on the interfacial chemical potential.

Al熔体中仅存在TiB_2粒子，而无多余溶质Ti时，α-Al在TiB_2粒子上异质形核产生的Al/TiB_2界面能大于α-Al从Al熔体中直接形核时的液-固界面能，不满足TiB_2粒子充当α-Al有效异质形核核心的能量条件，这从理论上解释了Al熔体内仅存在TiB_2粒子时无晶粒细化效果的实验现象。
