In order to investigate comprehensively the relationship between alignment index and road safety,the research puts forward the concept of road alignment synthetical index based on design indices such as curvature and its changing rate,curve angle,lognitudinal gradient,lane-width,lane number,and shoulder widths.

He also puts forward his classification of intensity indicator into composite indicator.

Research on comprehensive index of chilling damage to corn in Northeast China;

By comparing the advantages and disadvantages of their total content, available content and comprehensive index when they were used to evaluate their biological and ecological effect, this paper suggested that, many factors could influence the ecological effect of soil heavy.

This paper combined many influencing factors into a comprehensive index based on cause analysis,fuzzy set analysis and weights of factors.

Based on the prediction models and the domestic and foreign present status of the durability of HPC,the chloride ion resistance was used as an aggregative indicator to evaluate the durability of HPC.

Considering different aggregative indicators three classes as A,B and C are divided, at the same time the corresponding management system and mode are proposed.

Finally,combined with the both abilities,an integrated index of radar anti-jamming ability for active masking jamming is given.
