A magnificent phenomenon in major solar eruptions is the creation of along current sheet connecting solar flares to coronal mass ejections (CMEs). The sheet is important as the site where the magnetic energy is converted efficiently into heat and bulk kinetic energy and where particles are accelerated to high energy. With the development made recently in studying the CME/flare current sheet itself and particle accelerations in both theories and observations, our knowledge about the current sheet, its interior structures, and various processes occurring inside the sheet has been improved significantly. We are weaving various manifestations of solar eruptive processes related to the reconnecting current sheets, and looking into physical mechanisms that connect them to one another in the present work. Implications of these manifestations and the corresponding mechanisms to particle accelerations in the sheet are discussed, and some results we obtained recently for the particle acceleration are also displayed.
