摘要

With the help of a postulate of gauge group parameter involved with ghost fields,the infinitesimal gauge transformation laws preserving the gauge-invariance of the quantum Lagrangian itself of the quantized Glashow-Weinberg-Salam model are established precisely.The corresponding Ward-Takahashi identity for the model is derived exactly.
