摘要
In the mid-1980s, scientist A. Papyrin and his colleagues from the Institute of Theoretical and Applied Mechanics, the Russian Academic of Science in Novosibirsk, discovered some metal particles on the tunnel wall ,when they conducted wind tunnel experiments. The adhesion was not simple mechanical riveting, but they contained metallurgical bonding to some degree, and the bonding strength was very high.
