The authors calculated the highest temperature that may be attained by a single particle after passing through a shock wave.They found that the theory and the interpretation for experimental results,which was presented in the paper"The Pulverizing Effect of Shock Wave in Shock Wave in Supersonic Nozzle"(Vol.44,6,1993),are invalid.According to the experimental parameters of the above mentioned paper,a single particle can not crack after passing through a shock wave because of heating.
