中文摘要：

以辽宁阜新发电厂粉煤灰为例，进行了粉煤灰品质指标对所评价粉煤灰活性影响的灰色关联分析，结合规范和工程经验，建立了基于灰色系统理论的关于粉煤灰品质的多元灰色评价系统。研究结果表明，该评价系统能够全面客观地反映粉煤灰的实际活性与综合品质，可以此为依据实现对粉煤灰性能等级的准确评价。

英文摘要：

Take the fly ash of Fuxin power station for example the grey relational analysis about influence of fly ash quality indexes on activity of fly ash was given, the multivariate grey evaluation model about fly ash quality base on theory of grey system was established combining with specification and engineering experience. The results indicate that the evaluation system can reflect actual activity and comprehensive quality comprehensively and objectively, and can evaluate property level of fly ash accurately.
