摘要：

Fragmentation functions for hadrons composed of heavy quarks are calculated directly from the definitions given by Collins and Soper and are compared with those calculated in another way. A new fragmentation function for a P-wave meson is also obtained and the singularity arising at the leading order is treated in a new factorization form.
