运用运动学、统计学方法将刘翔与罗伯斯等国内外优秀运动员跨栏跑分段时间进行比较分析，同时将刘翔110米栏分段时间与他的总成绩进行相关关系研究。结果显示：在国内外优秀运动员中，刘翔在全程跨栏跑中，栏间三步跑优势明显，但刘翔的过栏腾空时间却不如国内外优秀运动员的平均水平，说明他的过栏腾空技术有待提高。与罗伯斯相比较，刘翔的优势是最后冲刺跑速度较快，不足之处是起跑到上第一栏时间和跨栏步腾空时间较长；刘翔起跑到上第一栏时间与总成绩的相关性最大，说明起跑到上第一栏是影响刘翔110米栏总成绩的最重要阶段，其次是跨栏步腾空阶段；刘翔要在今后的比赛中取得更好成绩，必须有针对性地加强起跑阶段和过栏腾空阶段技术训练。

Kinesiology and statistics are employed in this article to make a comparative analysis of the period time between Liu Xiang and other talent players including DayTon Robles. Meanwhile the correlation between Liu Xiang＇s period time and his total score is researched. Research findings show： compared with other talent players, Liu Xiang has an overwhelming advantage in the first three bars, but his clearing - the - bar technique still needs to be improved. Compared with Robles, Liu Xiang is better at the blast but poorer in from the start to the first hurdle and clearing -the -bar technique. The time needed in from the start to the first hurdle is greatly correlated to his total score, so is the cleating - the - bar technique. Liu Xiang must enhance technical training in the start stage and clear - the - bar technique to achieve better performance in the future.
