Abstract：
The total effective lagrangian of the gauge boson couplings to the neutral PG(Psudo-Goldstone)boson in technicolor models is developed.The effect of t-quark loop on the anomaly coupling is computed.Such effect significantly changes the coupling strength.The result is in favor of the detection of the neutral PG bosons.
