On Planck's mass

A brief review is presented of three fundamental physical quantities derived by Max Planck in 1912, referred to have as the Planck mass, Planck length and Planck time which had been arranged in the tables of 1986 and 1998 fundamental physical constants. Here the authors shall only discuss on Planck mass. Suppose that there is a quantized field of the nuclear forces in the nucleus with a quantum unit which the authors call the attrarepelon with a mass just equal to the Planck mass. Then the intensity ratio of the four interactions can be described quantitatively by their four coupling constants. A new method can then be found to measure the Newtonian constant of gravitation, G
