Abstract： A mechanism is presented for generating high speed particles in Herbig--Haro flow coming from accretion disks associated with
protostars. The disks are threaded with weak magnetic field lines, in which the magnetorotational instability results in magnetohydrodynamic turbulence. Then the turbulent waves accelerate the thermal particles out of the accretion disks to a few hundred kilometres per second, forming the high speed particles of optical jets in star-forming regions.
