- The saturation vapor curve is the curve separating the two-phase state and the superheated vapor state in the T–s diagram (temperature–entropy diagram). The is the curve separating the subcooled liquid state and the two-phase state in the T–s diagram. When used in a power cycle, the fluid expansion depends strongly on the nature of this saturation curve:
* A "wet" fluid shows a negative saturation vapor curve. If overheating before the expansion is limited, a two-phase state is obtained at the end of the expansion.
* An "isentropic" fluid shows a vertical saturation vapor curve. It remains very close to the saturated vapor state after an hypothetical isentropic expansion.
* A "dry" fluid shows a positive saturation vapor curve. It is in dry vapor state at the end of the expansion, and strongly overheated. (en)
- 飽和蒸氣曲線是在熱力學的温熵图（T–s圖）分隔二相狀態及過熱蒸氣狀態的曲線。 （saturated liquid curve）是在温熵图中分隔二相狀態及過冷液體的曲線。 在热力学循环中，流體的膨脹和飽和蒸氣曲線的特性有關：
* 「濕」流體會有負的飽和蒸氣曲線。在膨脹受到限制之前，流體已經過熱。在膨脹過程的最後，流體會是包括液態及氣態的兩相狀態。
* 等熵过程流體會有垂直的飽和蒸氣曲線。在假想的等熵过程後，仍非常接近飽和蒸氣的狀態。
* 「乾」流體會有正的飽和蒸氣曲線。在膨脹過程的最後，流體是在不帶液體的乾蒸氣狀態，是強烈過熱的狀態。 (zh)
