In this~qonference 127 representative., from 15 towns participated; 45 reports were presented anddiscussed. 11 of th .ese reports were devoted to different aspects of the problem bf absorption function. T4e discussions showed that at present two methods developed for calculating the absorptior furiction: the utilization of a spectrum model and the approximation of tho experimentE data determined by the standard'formulas, Also there are,two ways of approach to the pr9blem. of absorption function in case of an inhomogeneous medium: the mehho&of reduced mass and the method of weighted inean pressure. The problems of spectroscopy' of the absorbing components of atmosphere (water vapor,.ciu-bon dioAide 0ZIone, oxygen) were discussed on 8 conferences. The main attention was focusdd by the authors on A L 04685-67 A%.F- NKs Arowi-000 the obtaining of quantity data on the state., intensity a~d halfiridth of the aboorpqQr line of atmospheric gases, and on the analysis of the aontour,of line in h strong electromagnetic field. In 8 reports some theoretical problems associated'with the light dispersion in atmosphere were investigated. Modern problems inclWod the J attempt to interpret the transport equations from the point of view of electrodyruwd,cd and the analysis of the transport equations for unresolved absorption bands. 10 reports were devoted to the discusion of results pf;axperiawrital study of the light scattering by aerosols. 3 reports contained the d4ta ot tho transparency of atmoophere in various sections of spectrum and for differont:meteorological conditions. The description of the measuring instrumen~a was'given in 22.reparts. A summary of the analysis of modern experimental and the-oretical material about individual characteristics of t~B absorption lines of the main absorbing'components of atmosphere was presented by PTI.JomBld _yq ,y (S K.

The.authoirs investigated in detail the influonte mentioned in the title of this work and calculated the vel6 city,'of growth of the cracks by means of an objective method (reference 0) from the effective depth of the cracks. The kinds of rubber investigated are mentioned, This in~ostigation showed the following: 1.) With all coutchoues a qualitatively equal de9endende of the time passing till the fo~aation of craok~ on the intensity of deformation is obdoryad'-With grcwing~ : deformation this time gradually deerleases.to zero., 2#) The velocity of growth found for the steady range of the kinetic curve~initially iriOeasea with grolling,~ deformation, passes a maximum -within the rangelof small Card 1/3 deformations 6nd then decreases again. With all couitchoucs, Influence of the Degree of Deformation on the Pormation 20.,5-26/48 of Cracks in Rubber Caused by Ozone, and independent from their characteristio$.the period passing till the crack occurs pasees a minim~tm within the range of critical deformation and a maximum withiwthe range of great deformations if there i's a change of the deformation within the range of critical deformation. The re6ults obtained show the following: 1.) The strength of the rubbers in-the cane of multiple regularities obeys to the same regularity as with the formation of cracks by ozone. With all rubbers we observe a minimum of strength too. The destruction (formation of cracks) of deformed rubber b$means.of chemical interaction with ozone develops analogously with tht procese of static fatigue altho4h the velocities ot these processes differ by many:o,rders..From this follows the principal possibility of the accelerated investigation of the static fatigue of rubber, especially within the range of4mall deformations, by means of the formation of cracks depi6ndent on ozone* 2.)

A cenflAtive Indicator'of Influence of the Degree of Deformation on the 20-5-26/48 Formation of Cracks in Rubber Caused by Ozone* these changes is the resistance of rubberlagainst destruction in ozone.
