Abstract：
The relation between the masses of W ^±and Z ⁰in a composite model is disscused phenomenologycally. It is shown that any deviation of experimental data from the predicted value of W-S model will be in favour of the composite model.
By using present experimental data, the calculation results show that is W' (the radial excited state of W) exists, then its mass will be greater than (2 —5)m_w.
