Since the velocity of the flying spin-ring is 10 3 -10 4 km/s, in a tiny atom, the orbit is a belt. It prevents the spherical surface from compacting another pair of electrons. Therefore, as n>2, the remaining electrons must be designated to other orbits, i.e., the non-isothermal orbits. According to the relations of Le and r with T, the elliptic or the dumbbell-like orbit may be a rational choice. As shown in Fig. , the flying spin-ring shrinks to pass by the nucleus quickly. As a result, only a tiny portion of the orbits share a small isothermal spherical surface. The radii of different spheres should obey the square root law because the repulsive is r -4 , while the attractive is r -2 .
