摘要：
We study possible observational effects of the two Higgs doublets in the e(+)e(-), <b(b)over bar Z(0)> at the LEP II energy. We have found that the observational values can be obviously different from those predicted by the minimal standard model (MSM), but the results depend on the parameters of the extended model. The possibilities of the observation are discussed in some details.
