我们研究的星际中性（ISN）气体密度和拾取离子（PUI）密度的氢，氦，氖，氧在日光层的日心距离内1 Au太阳风终止冲击（TS），无论是在和出黄道平面。我们讨论的相似性和差异的大尺度结构的ISN气体和PUI在日光层中形成的各种物种之间。本文讨论了太阳活动周期的两个极端阶段，即太阳活动极小期和太阳活动极大期的ISN气体密度和PUI密度的分布。我们确定的位置的ISN气体密度腔的各种物种。我们研究了Ne/O、H/He、Ne/He和O/He的相对丰度比对ISN气体和PUI密度的影响及其在日球层中随位置的变化。我们还讨论了沿着TS的ISN气体和PUI相对丰度比的调制。我们的结论是，检测的He+和Ne+ PUI的优选位置是在下风半球内1 Au，而H+和O+ PUI的优选位置检测的距离从木星到冥王星轨道。
We study the distribution of the interstellar neutral (ISN) gas density and the pickup ion (PUI) density of hydrogen, helium, neon, and oxygen in the heliosphere for heliocentric distances from inside 1 au up to the solar wind termination shock (TS), both in and out of the ecliptic plane. We discuss similarities and differences in the large-scale structures of the ISN gas and PUIs formed in the heliosphere between various species. We discuss the distribution of ISN gas and PUI densities for two extreme phases of the solar activity cycle, it is the solar minimum and the solar maximum. We identify the location of the ISN gas density cavity of various species. We study the relative abundance ratios of Ne/O, H/He, Ne/He, and O/He for ISN gas and PUIs densities and their variation with location in the heliosphere. We also discuss the modulation of relative abundance ratios of ISN gas and PUIs along the TS. We conclude that the preferable locations for detection of He+ and Ne+ PUIs are in the downwind hemisphere within 1 au, whereas for H+ and O+ PUIs the preferable locations for detection are for distances from Jupiter to Pluto orbits.
