Strong interaction is no longer a short-range force

In 1935, Hideshi Yukawa proposed the feature of "short-range force" in strong interaction based on his quantum theory of nuclear physics. This was due to his mathematical formula expression,


which showed that after the distance r exceeds the nucleon radius, mcr/ћ becomes greater than 1 and accelerates the decline of the potential energy function φ. This proposal of the "short-range force" was then widely accepted in strong interaction. 

Recently, B. Feng's new physical theory has been used to study the strong interaction again. It has,

E = 4R1F(n)dn,

According to a large amount of generated data from it, the results expressed as near and far (even as far as n = 200 situations is considered) two distance region figures attached an analog function decaying with 1/r2, which nearly perfect closing was surprising to show that there is no short-range force in the strong interaction at all. Instead, 1/r2 is a normal decaying characteristic of long-range forces. However, strictly speaking, the characteristics of short-range force should exist, but only after a great distance of n = 200, according to calculation; to clarify, one could say that it is indeed a short-range force, but not a necessarily urgent.

It should also be noted that even in the long-range forces, the speed of decrease in space in the form of  1/r2 is also very fast. As can be seen from the first figure above, when the distance exceeds several times the radius of affected objects or particles, the force decreases to about only 10% of its previous level. Imaging that, satellites in the sky experience this situations all day long, isn't it?
