It is well known that neutral atoms or molecules of various origins, e.g. interstellar, cometary, or planetary, exist pervasively in interplanetary space. When these neutral particles get sufficiently close to the Sun, they can be ionized, for example by solar ultraviolet radiation. Consequently, the freshly created ions would interact with the moving solar wind. In recent years, research in this topic area has been spurred by in site observations at comets Giacobini-Zinner and Halley and attracted considerable interest and attention from the scientific community. I this work, a series of theoretical studies will be conducted relating to ion creation and structure in the solar wind. These include (1) further studies of ion pickup and subsequent development in a solar wind, (2) problems relevant to the stability and thermalization of ions in a pickup state, (3) and possible processes leading to assimilation of the newborn ions by the solar wind. Both analytical theory and numerical simulation techniques will be used in the proposed studies. ***

众所周知，各种中性原子或分子 起源，例如星际的，彗星的，或行星的，存在 在星际空间中无处不在。 当这些中立的 当粒子足够接近太阳时，它们可以被电离， 例如通过太阳紫外线辐射。 因此 新产生的离子会与移动的太阳风相互作用。 近年来，这一领域的研究受到以下因素的推动： 在贾柯比尼-辛纳彗星和哈雷彗星的实地观测中， 引起了科学界的极大兴趣和关注， 社区我在这部作品中，将进行一系列的理论研究 进行有关离子创造和结构在太阳能 风 这些包括（1）离子拾取的进一步研究， 太阳风的后续发展，（2）与 在拾取状态下离子的稳定性和热化，（3） 以及导致新生儿同化的可能过程 离子被太阳风吹走。 分析理论和数值计算 拟进行的研究将采用模拟技术。 ***
