摘　　要：互联网质量始终是网络运营过程中关注的重点问题。针对该问题,从真实下载速率角度切入研究,利用收集的大量网页浏览真实数据,详细分析了元素大小对下载速率的影响,以及下载速率的分布情况。然后提出通过页面元素下载1 Mbit/s以上速率占比来反映网络质量,并详细研究了元素大小限制对分析结果的影响。最后给出结论,使用1 Mbit/s以上速率占比反映网络质量时,必须剔除小元素的影响,元素大小限制以不低于10或20 kB为宜。The network quality is always one of the key issues on the network operation. In order to assess it more accurately, it starts its research from real download rate. Firstly, it uses a mass of factual web browsing data to analyze the distribution of page element download rates, and the relationship between element size and download rate. Then, it proposes using the ratio of rate higher than 1 Mbit/s to reflect the network quality, and researches the effect of element size limit on the analysis results. Final- ly, it reaches the conclusion that, when using the ratio of rate higher than 1 Mbit/s to reflect network quality, it must reject small elements firstly, and the recommend size limit is 10 or 20 kB.
