针对大规模嫦娥一号高能粒子数据,提出采用可视化分析其数据分布的一套方法.利用各时刻获取的粒子通量来图示高能粒子通量随时间的变化情况;并将一段时间内粒子通量分成若干区间,利用直方图显示不同通量范围内粒子数的统计分布;针对月表各点粒子通量所处的不同范围,给出月表不同通量区间内粒子分布的三维显示;基于月表各投影网格对应的平均粒子通量,给出月表平均通量分布的三维显示;通过引入月地日夹角参数,可视化随月地日夹角变化的通量分布.基于文中方法设计并实现一个高能粒子可视化辅助分析系统,对不同月份、不同种类的高能粒子数据进行快速浏览和分析,大大提高了对高能粒子分布数据的分析效率.
Aiming at the large-scale Chang’e-1 high-energy particle data, a set of methods for visualizing its data distribution is proposed, and the particle flux obtained at each moment is used to illustrate the changes of the energetic particle flux over time. In the meantime, Which is divided into several sections and the histogram is used to display the statistical distribution of the number of particles in different flux ranges. According to the different ranges of particle fluxes at each point in the lunar surface, the three-dimensional display of the particle distribution in different flux sections of the lunar surface is given. The average particle flux corresponding to each projection grid in the lunar surface is given a three-dimensional display of the lunar surface average flux distribution. Through the introduction of the included parameters of the lunar surface and the sun, the flux distribution of the angle variation with the lunar day is visualized. A high-energy particle visualization auxiliary analysis system is designed and implemented to quickly browse and analyze high-energy particle data of different months and different types, which greatly improves the efficiency of analyzing the data of high-energy particle distribution.
