Nondecoupling Effects of Heavy Higgs Particles in Two Higgs Doublet   Model
  Non-decoupling properties of additional heavy degrees of freedom in the Higgs sector of the Two-Higgs-doublet extension of the Standard model are discussed in a particular case of production of a pair of longitudinaly polarized W-bosons in the e^+e^- annihilation.
