传热原理在一般教科书都有讲解,但教科书都习惯于从理论的研讨开始。我觉得对于科技理论的学习,首先从物理现象上来了解、思索,比较直感,比较客易理解。对于传热原理,简单地讲,就是对导热系数(λ),给热系数(α),传热系数(K),这三个系数的理解。知道它们的来源、区别和关系,其它问题就迎韧而解了。 The principle of heat transfer in general textbooks have to explain, but textbooks are accustomed to starting from the theoretical discussion. I think for the study of science and technology, the first thing to understand from the physical phenomenon, thinking, more straightforward, more easy to understand. For the principle of heat transfer, simply speaking, is the thermal conductivity (λ), heat transfer coefficient (α), heat transfer coefficient (K), the understanding of these three coefficients. Knowing their origins, their distinctions and their relations, the other problems are solved.
