Wave equations for the dynamics of the ontogeny of linden leaves growing near a highway with intensive movement are given. The way of the analysis of parameters (lengths, width, perimeter and the area) for engineering biology and bioindication of the surrounding air environment is shown by oscillatory indignations of leaves. On the roadside, choose a tree and measure the distance from the middle of the root neck to the curb perpendicular to the road. In each zone a group of not less than 5 leaves is selected, mark...
