The skins are first soaked in pits filled with lime-water-that is, water with which some quick-lime has been mixed.

首先, 人们将毛皮（生石灰与水混合而成）石灰水中浸泡。

Ancient Greeks discovered the uses of various mixtures of petroleum, pitch, resins, sulfur, and quicklime as incendiary weapons, delivered by catapults, arrows, firebombs, and ships.

古希腊人发现了石油、沥青、树脂、硫磺和生石灰各种混合物作燃烧武器用途，通过弹射器、箭、燃烧弹和船只发射。

Limestone is refined to produce calcium oxide, or quicklime, for cement, in a reaction known as calcination, which releases a lot of carbon in the form of CO2.

石灰石被提炼以生产用于水泥氧化钙或生石灰， 在称煅烧中，该以 CO2 形式释大量碳。

Moreover, the distribution and the shape of the clumps suggest that the lime was added to the mix as quicklime, rather than, as is common today, slaked (hydrated) lime.

此外，凝块分布和形状表明， 石灰是以生石灰形式加混合物中，而不是像今天常见那样， 以消石灰（熟石灰）形式加。

此外， 团块分布和形状表明， 石灰是以生石灰形式加到混合物中，而不是像今天常见熟石灰或消石灰。

This would mean that Roman concrete was made, at least partly, by hot mixing, for slaking quicklime with water releases enough heat to raise the temperature of a concrete mix above 80 degrees Celsius.

这表明罗马混凝土至少部分是通过热混合法制作，因生石灰与水释热量足以将混凝土混合物温度提升至80摄氏度以上。
