1) Many QM text books showed that the matter wave has the relationship of v(n,ph) = (1/2)v(n,gr), my research result suggested that v(n,ph) = (n/2)v(n,gr) may be the more Eigen description. My research result revealed that the non-Born probability (NBP) or de Broglie wave can be used for either the group wave, or the phase wave. My research result also revealed that it is the phase wave that reflects each single electron/object’s true matter wave property, the group wave only reflects the property of all electrons/objects as a group. 2) The paired up/down spin information of the electron and the nucleon may have already been presented by the positive/negative wave peaks (of the phase wave) in either the Schrodinger equation/solution (in form of NBP), or in the de Broglie wave in the Bohr H-atom model. 3) The spin of both the electron and the nucleon (in an atom) may originate from the face-to-face tidal-locked binary circular orbital rotation between them. This hypothesis also perfectly fits to the new "proton-electron mirror-coupled orbit" model (in SunQM-6s6). The result of Bohr-QM formula L(n,orbit) = mv(n)r(n) = nℏ may directly support this hypothesis. 4) Ultimately, the real meaning of spin ½ℏ for an electron may be: the electron always has an effective orbital angular momentum (between the inner and outer edges of the n shell) that is ½ℏ higher than the value at the inner edge of the n orbit. And because of the face-to-face tidal-locked, this ½ℏ effective orbital angular momentum is carried over by the electron as the electron’s effective spin angular momentum. 5) For a pair of spin up/down electrons, their (electron-proton face-to-face tidal-locked) orbital movement in φ-1D (in the opposite ±m directions) may have transformed into a uni-directional orbital movement in θ-1D. 6) A spin configuration for each of the four nucleons in an alpha particle has been proposed. 7) Planets’ spin origin may also can be explained by using the similar Bohr-QM formula L(n,orbit) = mv(n)r(n) = nℏ(gen) (that is specified for the Solar system). 8) This analysis again showed that, the quantum phenomenon is produced by the interference of the 3D spherical wave of a point-centered field (of force, mass, energy, etc.) to become a spherical 3D wave packet, so that the NBP (= wave) peaks at some positions and valleys at some other positions.
