闪点 ＝ 可燃液体能放出足量的蒸气并在所用容器内的液体表面处与空气组成可燃混合物的最低温度 ，蒸气闪火时的温度。

Flash point = The minimum temperature of a liquid at which it gives off vapors sufficient to form an ignitable mixture with the air near the surface of the liquid or the container. Flash point is by far the most important property to understand regarding flammable/combustible liquids. Aka the temperature which there’s enough vapor to flash.
