摘要：

An effective Lagrangian that describes the low-momentum interactions of mesons containing a heavy quark with the pseudo Goldstone bosons pi, K, and eta is constructed. It is invariant under both heavy-quark spin symmetry and chiral SU(3)L x SU(3)R symmetry. Implications for semileptonic B and D decays are discussed.
