Abstract：
By re-analyzing the results of the theoretical abundance of AGB stellar models and the observed abundances of 51 AGB samples, we find that the abundance distribution of heavy elements belonging to the main-component of slow neutron capture process (SMH elements) of any AGB star is similar to that of the scaled s-process main component of the solar system. It means that superposition of the SMH element abundance distributions of AGB stars should be similar to that of the scaled solar s-main component. As a conclusion, the heavy element abundance pattern of the solar s-main component is a typical one and can be used as a standard in the investigation of heavy element abundances in single star.
