Abstract：
Motivation of the Touschek backgrounds study is introduced. Also introduced are the theory and modeling methods of the Touschek effect. The Touschek backgrounds of the main detectors of the BESⅢ are studied in detail using the self-reprogrammed general simulation tools. Comparison of the beam lifetime between the simulated and calculated ones shows that the simulations are reasonable and the results are meaningful. Results of the detectors' backgrounds show that the Touschek backgrounds won't affect the normal run of the future BESⅢ and won't damage the main detectors.
