In developing the {N,n} QM field theory, from the pure quantum mechanics (QM), I deduced out a positive precession for the circular orbital motion (see in SunQM-4). In the current paper, I used this positive precession to explain 1) the Mercury’s perihelion precession; 2) the fast-flow zonal band on Jupiter’s atmospheric surface. Then, using a newly developed concept (i.e., the "face-opposite-face locked binary orbital motion" in φ-1D bi-direction with the anti-parallel spin will automatically transform to be a θ-1D orbital uni-directional motion, see in SunQM-6s10), I further developed this positive precession to be a positive/negative precession cycle (also called the "Ylm cycle"), and it is driven by the half-cycle of m > 0 and half-cycle of m < 0 in the nLL QM state of the |n,l,m>. Then, I used it to explain the elliptic orbit motion (an Ylm cycle with the acceleration/deceleration cycle), the sunspot drift (an Ylm cycle with a period of 22 years), the continental drift (an Ylm cycle with a period longer than 10^5 years), etc. The results of these analysis made me to further hypothesize that: the residue nLL QM state’s positive/negative precession may even be the origin of all elliptic/parabolic/hyperbolic orbits (including the gravitational lensing that belongs to a hyperbolic motion). It may be possible to use QM’s positive precession at different (and combined) high-frequency n’ to fully explain Mercury’s perihelion precession (without using classical physics and/or general relativity (GR)). This work revealed that in a circular/elliptical orbital motion, QM not only may (intrinsically) generate a positive precession, but also may (intrinsically) generate a positive/negative precession cycle (i.e., the Ylm cycle). This work may also suggest that the QM and the GR are the two "faces" of the same "master mechanics". Finally, because of its completeness and self-consistence, I do believe that the {N,n} QM is qualified to be put into the "Feynman Pool" as one of the many co-existing QM theories.
