	Abstract:We study the full contributions at the leading order(LO) and QCD next-to-leading order(NLO) to the cross section of the $e^+e^- \to W^+ W^- b\bar b$ process in the standard model(SM) at the ILC. In dealing the resonance problem we adopted the complex mass scheme in both tree-level and one-loop level perturbative calculations. Our numerical results show that the K-factor varies from $1.501$ to $0.847$ when $\sqrt{s}$ goes up from $360~GeV$ to $1.5~TeV$. We investigate the dependence of the LO and QCD NLO corrected cross sections of process $e^+e^- \to W^+ W^- b\bar b$ on colliding energy $\sqrt{s}$ and Higgs-boson mass. We also present the results of the LO and QCD NLO corrected distributions of the transverse momenta of final particles, and the invariant masses of $Wb$-, $b\bar b$- and $WW$-pair.

	Abstract:We add a nonstandard higgs into the traditional bosonic part of electroweak chiral Lagrangian, in purpose of finding out the contribution to EWCL coefficients from processes with internal line higgs particle. To construct the effective Lagrangian with higgs, we use low energy expansion scheme and write down all the independent terms conserving $SU(2)\times U_Y(1)$ symmetry in the nonlinear representation which we show is equivalent to the linear representation. Then we integrate out higgs using loop expansion technique at 1-loop level, contributions from all possible terms are obtained. We find up to order of $p^4$ in low energy expansion, three terms, $\mathcal{L}_5$, $\mathcal{L}_7$, $\mathcal{L}_{10}$ in EWCL are important, for which the contributions from higgs can be further expressed in terms of higgs partial decay width $\Gamma_{h\rightarrow ZZ}$ and $\Gamma_{h\rightarrow WW}$. Higg mass dependence of the coefficients in EWCL are discussed.
