По экспериментальным данным было сделано заключение о закономерности образования трещин. Среднее значение количества трещин было принято в качестве степени растрескивания. Было показано, что скорость роста трещин состоит из двух частей: относительно медленная в начале испытания и высокая на втором этапе. Работа выполнялась при постоянной скорости. Было дано объяснение экспериментальных данных и кинетического закона процесса. Было рассчитано количество озона необходимое на формирование трещин площадью 1см 2,, обнаружено, что это количество равно ≈8·10 -10мол/см 2, что составляет около 1% от общего количества поглощенного озона.

The regularity of cracks formation had been concluded from precise experimental data. The mean value of crack surface was used as a measure of cracking degree. It was shown that the rate of cracks surface growth consists from two stages: a relative slow one at beginning of test and a faster one on the second stage. It was running with constant rate. A probable explanation of experimental observation and kinetic law of process was given. It was counted of the amount of ozone consumed per 1 cm 2 of forming cracks surface, which was found to be ~8 x 10 -10 mol/cm 2, what is about 1% of the total amount of ozone absorbed by the sample.
