自从迈耶尔和黑姆霍兹发现了“能量守恒定律”之后,人体是否也遵循这一定律的问题便引起了人们极大的注意.直到上个世纪末,出鲁本厄用精确的平衡实验,证明了这一定律对生物也完全适用.从那时起,人体需要能量和能量代谢的观点才被确立起来.热能的基本概念从物理化学的角度来讲,可以把人体看做是一个能量转换和传递 Since the discovery of “law of conservation of energy” by Meyer and Helmholtz, great attention has been paid to whether or not the human body follows this law. Until the end of the last century, , Proved that this law is also fully applicable to the creature since then, the human body needs the idea of ​​energy and energy metabolism was established. The basic concept of thermal energy from the physical and chemical point of view, the human body can be seen as an energy Conversion and delivery
