摘要：
Some data on the ratio of vector to vector + pseudoscalar mesons, V/(V + P), and the probability of helicity 0 vector states, rho(00)(V), are now available from LEP. A possible relation between such two quantities and their interpretation in terms of polarized fragmentation functions are discussed; numerical estimates are given for the relative occupancies of K and K*, D and D*, B and B* states.
