摘　　要：材料数据是材料基因组计划的三大核心工具之一,近年来在国际上引起强烈关注,美国、日本等国相继资助了大型数据库建设和数据分析的项目。材料数据的准确性与完整性,是数据分析与挖掘的根本保障,并直接影响材料数据库的建设以及材料数据价值的深度开发和应用。材料大数据的特征主要表现在材料属性的高维以及属性间的复杂关联关系,在材料数据分析挖掘中应重视与材料领域知识的充分结合,以及离群点分析上的学科特点及需求特殊性。而材料数据相关的基础教育,尤其是在本科阶段数学与计算机相关基础课程的设置,则成为今后材料数据成为材料创新发展手段的保障。本文就材料基因工程框架下材料数据长久发展进程中目前亟待重视和解决的问题加以讨论。The materials data is one of the three key tools in materials genome initiative （MGI） , which has been attrac- ting great attention worldwide. Projects on large scale databases construction and data mining have been implemented in US, Japan and other countries. The accuracy and integrity of the materials data are the foundation of data analysis and min- ing and they will directly influence the quality of database construction and deep extraction of the data value. The main fea- tures of materials data are high dimensions of materials attributes and complex interactive relationships. It＇s worth noting that the data mining should be associated with domain knowledge of materials and the typical requirement of materials on the outlier analysis. Education on materials data and related disciplines, especially the college education on math and IT technology, will be the basic guarantee for the data being as the paradigm of innovation. The problems to be settled con- ceruing the long term development of materials data were discussed in this paper.
