Dielectric relaxation measurements by the use of a time domain reflectometry method were performed on Soleus Muscle and Gastrocnemius Muscle of wistar rat in a temperature range of 0℃ to 40℃. Three dielectric relaxation peaks could be found. The low frequency peak around 100Hz could be assigned to electrode polarization, and the intermediate one around 100kHz could be attribute to migration of counterion on biomaterial. The high frequency one around 10GHz could be due to orientation of water molecules, judging from the relaxation time and relaxation strength. Its activation energy obtained from temperature dependence of the relaxation times is 16kJ/mol, which is in good agreement with that of pure water. Water content estimated from its relaxation strength at 25℃ is about 0.7/cc. There is a large amount of bulk water in the muscle cell.
