다음을 풀어보세요: {l}{eta_{s}=Deltah/(Deltah)_{s}=frac{h_{1}-h_{2}}{h_{1}-h_2^prime}}{=3194.7-2577.1/3194.7-2259.9=0.661}

$$\left. \begin{array}{l}{ \eta _ { s } = \frac { \Delta h } { ( \Delta h ) _ { s } } = \frac { h _ { 1 } - h _ { 2 } } { h _ { 1 } - h _ { 2 } ^ { \prime } } }\\{ = \frac { 3194.7 - 2577.1 } { 3194.7 - 2259.9 } = 0.661 }\end{array} \right.$$

η_s, Δ, h, s에 대한 해 (complex solution)

$$s\in \mathrm{C}$$

$$\eta _{s}=s$$

$$\Delta \in \mathrm{C}$$

$$h\in \mathrm{C}$$

η_s, Δ, h, s에 대한 해

$$s\in \mathrm{R}$$

$$\eta _{s}=s$$

$$\Delta \in \mathrm{R}$$

$$h\in \mathrm{R}$$
