摘要
目的研究加热治疗皮肤疾病时的温度场分布情况,从而为实验研究提供一定参考。方法本文在假设直接接触皮肤加热的情况下,从皮肤的结构出发建立起物理模型,根据生物传热学的理论,建立传热方程,采用有限差分方法对各种情况进行仿真。结果仿真得到了加热时皮肤的稳态温度场和动态温度场分布情况,结果证实直接接触加热治疗皮肤疾病这一技术具有可行性。结论本文的研究结果对进一步研究和利用精确控温下直接接触加热治疗皮肤病技术有一定参考意义。
Objective To study temperature field distribution for hyperthermia of skin diseases with direct heating,and this helps develop experimental research.Methods In the condition skin be direct heated,we set up physical model of the skin and bio-heat transfer equations based on the structure of the skin and bio-heat transfer theories;simulated temperature field distribution in different situations by the method of finite differences.Results Simulation results of both steady and dynamic temperature field distribution confirmed the possibility of curing skin diseases by heating it.Conclusion Our results will be useful for deeper research and use of hyperthermia of skin diseases with accurate temperature control by direct contact heating.
