Gibbs' H theorem - Gibbs's Ecchi Theorem

…However, if the value of ρ before taking the limit ⊿Γ→0 is P in the definition of ρ, the sum P log P of all the infinitesimal parts will reach its minimum value when ⊿Γ→0 after taking the limit t →±∞. This is Gibbs' H theorem. In the case of microscopic density ρ, we first set ⊿Γ→0, so the value does not change even when t →±∞. …

*Some of the terminology explanations that refer to "Gibbs' H theorem" are listed below.

Japanese:

…しかし,ρの定義で⊿Γ→0の極限をとる前の値をPとすると,すべての微小部分についての和PlogPt→±∞の極限をとった後で⊿Γ→0とすると最低値をとる。これがギブズのH定理である。微視的密度ρのときは先に⊿Γ→0とするからt→±∞でも値を変えなかった。…
