我在网路上有找到一篇journal:Electric burns: high- and low-tension injuries 里面有一段话 The electric current through the tissues turns electri- cal energy into heat, the Joule effect. The main source of damage by the electric current in the tissues is due to this conversion of the electrical energy into heat. The amount of heat can be determined by Ohm's law and the Joule effect. Ohm's law states that the current travelling through tissue is determined by voltage divided by resistance. Tissue resistance progressively increases from nerve, to blood vessels, muscle, skin, tendon, fat and bone. Bone, having the greatest resist- ance would generate most heat at the same current according to the Joule effect. However the high-resist- ance of bone suggests that current would be lower in the bone than in other tissues. Blood vessels are injured but may not be immediately thrombosed; and this damage may lead to progressive ischemic necrosis of the muscle as a result of the injury [1,2]. 如果按照这篇文章讲的答案好像好像是boneㄟ 可是又有人跟我说因为E=V2/R R越小E越大...所以我不知道答案到底是什麽... 而且这篇文章还有提到 nerve电阻才是最小的喔 eMedicine Specialties > Plastic Surgery > Burns里的complication 中也有一段话 Bone has a high resistance, thus readily transforms current to heat production, which may result in periosteal necrosis or even melting of the calcium phosphate matrix. --
