In order to research the spray of LPG/diesel mixed fuel, it is the first time that this work studied the atomization characteristics of LPG/diesel, including spray angle, droplet size distribution, mean diameter, typical diameter, diffusion degree and impenetrate distance by using a high spatial resolution digital camera. At the same time, comparison of these characteristics of diesel and two kinds of LPG/diesel mixed fuel was taken.

Consequently, the vertical TEC around the receiving station was exported. Through this method, the vertical TEC got is an average value of a prick angle around the vertex. With the statistics of dispersion and the high precision data collected in Kunming station, the authors calculated the day by day time sequence value of total electron content in altiplano zone ionosphere. Based on this, they described the characteristics of TEC Sunday-changing in double-hump zone, comparing with CORS of Kunming.

这种方法得到的垂直TEC为天顶周围一锥角内的平均值，通过离散度的统计，并结合昆明站采集得到的高精度数据计算了该地区电离层2007年6~8月的电离层电子浓度总含量的逐日时间序列值，在此基础上对照昆明市连续运行参考站CORS描绘出了对于处在双驼峰区里该地区TEC日变化的特性。
