By re-analysing the results of the theoretical abundance of asymptotic giant branch (AGB) stellar models and the observed abundances of 51 AGB samples, we find that the abundance distribution of s-process main heavy (SMH) elements of any AGB star is similar to the scaled s-process main component of the solar system. This means that superposition of the SMH element abundance distributions of AGB stars should be similar to the scaled solar s-process main component. As a conclusion, the abundance pattern of the solar SMH elements is not only an average result of a complex chemical evolution of galaxy, but also a typical one that can be used as a standard in abundance investigation.
