Abstract：
In virtue of the simple physical picture of quark combination model and the probability for the production of a q_fq_f of a flavor f which is given by treating the pair creation of the qq as a quantum mechanical tunneling effect, an universal mass relation for direct hadron production rates, =Aexp(-bm), is obtained without any additional assumption. It is satisfied by various high energy reactions. This universal mass relation is in agreement with a simple empirical regulation proposed recently and is independent of the mass-center energy and the process of the reactions. This suggests that the mass of hadrons is the primary factor for describing the particle multiplicities.
