Introduction Ⅰ.Problem 3rd virial coefficient across an Efimov threshold,divergent behavior Spectrum of 2+1 system Ⅱ.Methods hyperspherical formalism harmonic regulator 3-body boundary condition model Ⅲ.Results no divergence for 3rd virial coefficient!Important role of 3-body parameter(3BP) without Efimov effect.Third virial coefficient is a smooth functionacross an Efimov threshold.3-body boundary condition model describes the systemuniformly both below and above the threshold.3BP is important even below the Efimov threshold,over a significant interval of mass-ratio.
