Magnetic reconnection is an important and frontier topic in the realm of physics. Various physical phenomena can be observed during the reconnection process but lots of them are not fully understood. This thesis provides the first observational evidence of energetic electrons associated with magnetic reconnection in the solar wind and discusses the particle acceleration problems. In addition, after analyzing the particle flux variations in Magnetic Cloud Boundary Layer, the thesis proposes a possible new criterion for the identification of magnetic reconnection in the solar wind. These tantalizing results could be particular clues to understand the dynamical problems in magnetic reconnection processes.Springer Theses, Recognizing Outstanding Ph.D. Research,2190-5053GeophysicsSpace sciencesPlasma (Ionized gases)Geophysics/Geodesyhttps://scigraph.springernature.com/ontologies/product-market-codes/G18009Geophysics and Environmental Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P32000Space Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics)https://scigraph.springernature.com/ontologies/product-market-codes/P22030Plasma Physicshttps://scigraph.springernature.com/ontologies/product-market-codes/P24040Geophysics.Space sciences.Plasma (Ionized gases).Geophysics/Geodesy.Geophysics and Environmental Physics.Space Sciences (including Extraterrestrial Physics, Space Exploration and Astronautics).Plasma Physics.551.5153Wang Yiauthttp://id.loc.gov/vocabulary/relators/aut927188MiAaPQMiAaPQMiAaPQBOOK9910254122303321Magnetic Cloud Boundary Layers and Magnetic Reconnection2508104UNINA
