Mathematical analysis reveals that the UV cutoff results in the minimum structures of space. Dominated by rotational symmetry, the structure should be a local one in situ or on a sphere. Investigations show that a 10D minimum structure is a non-local one with transformability between in-situ state and spherical state due to its special topology. Based on the quantum behaviors of the 10D structure controlled by translational symmetry, IR cutoff determines two long-range interactions with dimensionless constants of ~1/137.036 and ~1/1.628E+38, respectively. %K Planck Length %K IR Cutoff %K Symmetry %K Fine Structure Constant (FSC) %K Quantum Gravity %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=140206
