主　　题：Skin erythema thermal entropy enthalpy 

摘      要：The molar entropy(OS)and molar enthalpy(△H)for the denaturation event that triggers cutaneous erythema was determined to be △S=190J/(mole K)and△H=146.9×10^(3) J/*** experiment involved placing heated water against the skin of the forearm,for a range of termperatures and exposure *** the skin to 45℃ for 22 s was at the threshold for producing erythema,which was similar to the threshold for a slight degree of pain.
