摘要
目的将熵增加原理应用于生命现象,对探究生命现象具有重要意义。方法从能量转化和传递的角度,研究人体生命过程中限制能量摄入与延长寿命的关系。结果人的生命过程是不可逆过程,也是熵增加的过程,当熵达到最大值时,则会出现热力学平衡态,即物理意义上的死亡。结论为了延长人的寿命,可以在中年后通过限制能量摄入方式减缓熵增加的速率,从而延长寿命。
Objective Entropy is an important and basic concept in physics.The application of entropy and its principle has important significance.Methods The relationship between dietary energy restriction and life extension in biotic process of human body from the energy transforming and transfering was studied.Results The life process is irreversible,and it is also an entropy increasing process.When entropy comes to the peak value,the thermodynamic equilibrium state will occur,namely the physical meaning of death.Conclusion Slowdown of entropy increasing from dietary energy restriction can prolong life.
