计算公式

可避免?损与不可避免?损

${\dot{E}}_{D, k} = {\dot{E}}_{D, k}^{U N} + {\dot{E}}_{D, k}^{A V}$

$\begin{array}{l} {\dot{E}}_{D, k}^{U N} = {\dot{E}}_{^{P, k}}^{R E A L} {(\frac{{\dot{E}}_{D, k}}{{\dot{E}}_{P, k}})}^{U N} \\ {\dot{E}}_{D, k}^{A V} = {\dot{E}}_{D, k} - {\dot{E}}_{D, k}^{U N} \end{array}$

内源性与外源性?损

${\dot{E}}_{D, k} = {\dot{E}}_{D, k}^{E X} + {\dot{E}}_{D, k}^{E N}$

$\begin{array}{l} {\dot{E}}_{D, k}^{E N} = {\dot{E}}_{^{P, k}}^{R E A L} {(\frac{{\dot{E}}_{D, k}}{{\dot{E}}_{P, k}})}^{E N} \\ {\dot{E}}_{D, k}^{E X} = {\dot{E}}_{D, k} - {\dot{E}}_{D, k}^{E N} \end{array}$

四部分?损

${\dot{E}}_{D, k}^{U N, E N} = {\dot{E}}_{P, k}^{E N} {(\frac{{\dot{E}}_{D, k}}{{\dot{E}}_{P, k}})}^{U N}$

${\dot{E}}_{D, k}^{U N, E X} = {\dot{E}}_{D, k}^{U N} - {\dot{E}}_{D, k}^{U N, E N}$

${\dot{E}}_{D, k}^{A V, E N} = {\dot{E}}_{D, k}^{E N} - {\dot{E}}_{D, k}^{U N, E N}$

${\dot{E}}_{D, k}^{A V, E X} = {\dot{E}}_{D, k}^{E X} - {\dot{E}}_{D, k}^{U N, E X}$
