生物活体组织在一定情况下受外界加热而发生温度振荡的本实是生物传热领域内长期得不到合理解释的经典问题,本文深入考察了生物传热的真实特点,将逻辑上更为严明的热波理论引入Pennes生物传热方程,获得了新的生物传热模型,在一定条件下导出了由外界加热而诱发体内温度振荡所应满足的准则及振荡周期,所得结果清晰地表明了只有生物体可能出现温升振荡而非生物体则不可能的原因。本文提出的热波学说深化了对生物体温升振荡效应的认识,首次揭示出,生物体之所以发生温升振荡,关键原因并非通常所认为的外界加热方式以及生物体所具有的诸如心理因素、自调节特性等影响条件,而在于生物活体本身所团有的血液对流换热模式及其内部的有限热传播速度。本文是目前唯一严格的用于解释温升振荡现象的理论尝试。
Bio-living tissue under certain circumstances by external heating and temperature oscillation of this fact is the field of biological heat transfer can not be a reasonable long-term classic problem, this paper examines in depth the true characteristics of biological heat transfer, the logic is more stringent The thermal wave theory is introduced into the Pennes equation of heat transfer and a new biological heat transfer model is obtained. Under certain conditions, the criterion and oscillation cycle that should be satisfied when the body temperature is induced by external heating are derived. The results clearly show that only Organisms may be temperature oscillation rather than organisms are impossible reasons. The heat wave theory proposed in this paper deepens our understanding of the temperature rise and oscillation effect of organisms. It reveals for the first time that the reason why the temperature rise and oscillation occurs in the organisms is not the commonly accepted external heating method and the biological factors such as psychological factors, Self-regulating characteristics and other conditions, but rather the biological living body itself, the blood convection heat transfer mode and the limited internal heat propagation speed. This article is the only rigorous attempt to explain the phenomenon of temperature oscillations.
