反应平衡参数

请问下高手，这里的参数代表什么意思。在哪里可以查到相关的参数。

平衡常数定义


Enter coefficients for the built-in equilibrium constant expression:

   ln (K ) = A + B / T + C *ln (T )+ D *T + E(P-Pref ) / Pref
Where:


Enter coefficients for the alternative equilibrium constant expression based on the van 't Hoff equation, which is indifferent forms for equilibrium reactions and for salts:
    ln (Kequil ) = -HREAC /RT * (1 - T /TREF ) + ln(KREF ) + E (P-Pref ) /Pref
    ln (Ksalt ) = -HFUSION /RT * (1 - T /TMELT ) + ΔCP/R * (TMELT /T - 1) - ΔCP/R* ln(TMELT /T ) + E (P-Pref) /Pref
Where:



The definition of K depends on the concentration basis selected. You canoptionally choose a different concentration basis for each reaction.
Repeat steps 6 and 7 for all equilibrium reactions and salt precipitation reactions included in the Chemistry ID. Because complete dissociation reactionsdo not require equilibrium constants, nothing on the Equilibrium Constants sheet applies to reactions of this type.

就是拟合常数，你有实验数据自己也可以拟合啊
