摘要	Using a population synthesis code, we have investigated the formation of symbiotic systems in which the hot component is a main-sequence star that is accreting matter from the cool component via Roche lobe overflow (RLOF). The RLOF can be divided into two cases: dynamically unstable and stable. In the first case, the birthrate of symbiotic stars is 0.056 yr(-1) or 0.045 yr(-1) depending on different assumptions; in the stable RLOF case, it is 0.002 yr(-1) 0.005 yr(-1). The number of symbiotic stare with main-sequence accretors and unstable RLOF in our galaxy is about 5, that with stable RLOF is about 60 to 280. Comparison between our results with those of Yungelson et al. shows that symbiotic stars with MS accretors make only a small contribution (less than or similar to 8%) to the whole population of symbiotic stars in the Galaxy.
