Abstract: First, we discuss quantitatively a hypothesis that the masses of four fundamental particles are direct proportion to the strengths of four interactions. From this we obtain that the rest mass of photon is about 7×10 -32 eV. Next, based on a modified more accurate GMO mass formula M=M 0+AS+BI(I+1)-(S 2/2) proposed by us, the relations between the parameters in the formula and the strengths of interactions are calculated. Finally, some formulas of particles and their relations with the strengths of...
