Abstract：
A new approach of the kinematic fit in event reconstruction is introduced.In the new approach, the method of regula falsi is used to solve the constraint equations, instead of the conventional linear approximation. Applying this algorithm to E705/E771 Monte Carlo data of J/ψ→μ⁺+μ^－,the momentum resolution of J/ψ is significantly improved.
