    摘要:

    平流层飞艇有着广泛的功能和用途,随着科技的飞速发展,世界上掀起了研究和开发平流层飞艇的热潮.综述了国内外对平流层飞艇空气动力学问题的研究现状及未来的发展趋势,讨论了目前研究中需要解决的一些关键技术.在此基础上,总结出今后研究的重点,并为平流层飞艇的设计提供了参考依据.

    Abstract:

    According to traffic safety and driving quality of exposed-aggregate cement concrete pavement,through carrying out a large number of laboratory test and constructing trial road and testing it,the article analyzes major evaluation indexs such as number of exposed-aggregate point,texture depth,pavement driving-noise,surface level of exposed-aggregate.Mutual relations among exposed-aggregate point,texture depth and surface anti-skidding performance are illuminated,meanwhile,test methods and appraisal degrees to specific major evaluation indexs are researched respectively.It is vitally meaningful to assure or improve quality of exposed-aggregate cement concrete pavement.
