In a note to What is Life? Schrödinger explained his use of this phrase.
In a note to What is Life? Schrödinger explained his use of this phrase.
在《生命是什么？》的一项注释中，薛定谔解释了他使用这个短语的原因。
{{cquote|... if I had been catering for them [physicists] alone I should have let the discussion turn on ''[[Thermodynamic free energy|free energy]]'' instead. It is the more familiar notion in this context. But this highly technical term seemed linguistically too near to ''[[energy]]'' for making the average reader alive to the contrast between the two things.}}

如果我只是迎合物理学家们，那么我就该让讨论转向<font color="#ff8000">“[[热力学自由能|自由能 free energy]]”</font>。在这个语境中，自由能是物理学更熟悉的概念。但是，这个高度专业的术语在语言学上似乎太接近于<font color="#ff8000">能量 energy</font>，以至于普通读者无法生动地看到两者之间的区别。
In 2009, Mahulikar & Herwig redefined negentropy of a dynamically ordered sub-system as the specific entropy deficit of the ordered sub-system relative to its surrounding chaos.<ref>Mahulikar, S.P. & Herwig, H.: (2009) "Exact thermodynamic principles for dynamic order existence and evolution in chaos", ''Chaos, Solitons & Fractals'', v. '''41(4)''', pp. 1939–1948</ref> Thus, negentropy has SI units of (J kg<sup>−1</sup> K<sup>−1</sup>) when defined based on specific entropy per unit mass, and (K<sup>−1</sup>) when defined based on specific entropy per unit energy. This definition enabled: ''i'') scale-invariant thermodynamic representation of dynamic order existence, ''ii'') formulation of physical principles exclusively for dynamic order existence and evolution, and ''iii'') mathematical interpretation of Schrödinger's negentropy debt.
