Many infiuences of physical, chemical and geometrical properties of the diffused substances on the Lagrangian correlation coefficient for the turbulent diffusion in a wind tunnel flow are considered theoretically. Influences of the decaying phenomena of a wind tunnel turbulence are also taken into consideration. Influences of these factors on the Lagrangian smallest eddy λn introduced by Sir Geoffrey Taylor are discussed in detail making use of the concept of the smallest turbulon ∧_∞v^<3/4>ε^<-1/4> due to the similarity theory of turbulence, where v and e mean the kinematic viseosity of a fluid material and the dissipation rate of turbulon energy respectively.
