Abstract：
In the framework of perturbative QCD,the exclusive decays $\Upsilon\to B\bar B$(B:baryon) are studied.With the constituent quark model describing the charm-baryonic structure, we calculate the decay widths for $\Upsilon\to p\bar p,\Lambda_c\bar \Lambda_c,\Sigma_c\bar \Sigma_c,\Xi_c\bar \Xi_c,\Xi_{cc}^+\Xi_{cc}^-,\occc\bar \occc $ , and discuss the prospect to search for the charm baryon $\occc$ in $\Upsilon$ decays.
