Since our main point of interest will be the upper tail of the city size distribution it can be argued that their exclusion does not matter too much for our analysis.

并且由于我们研究的主要兴趣在于城市规模分布的上扬的尾部，所以，那些被剔除的数据对我们的分析没有太大的影响。

All above results are very important for particle size and distribution analysis. And these results have been successfully applied to measure the droplet field of nozzle atomization.

这些结果，对分析粒子的大小和分布是十分重要的，并在喷嘴雾化场测试中得到了应用。
