Abstract
Based on the observations of the individually typical element abundances of metal poor stars and the solar heavy nuclide abundances of the r process and s process, the abundances of the heavy elements in metal poor stars HD 203608 and HD 211998 are calculated. The comparisons between the calculations and the observations shown that, the observations of the two stars can not be matched by the pure r process or pure s process abundance distributions of the solar system, while they can be better fitted if the contributions of the solar r process and s process were considered together.
