But when the tweakers took over the efficiency of the steam engine swiftly quadrupled.

但是当巧匠们接手之后，蒸汽机的效率一下子变成了四倍。

Most of the gains in efficiency come from increasing the heat and pressure of the steam used to turn a plant's turbines.

多数借由提升燃烧效率带来的利益是依靠对用以驱动发电站涡轮机的蒸汽进行升温和加压。

For high efficiency, the steam must decrease substantially in temperature as it expands within the engine.

蒸汽在发动机中膨胀后，温度必须大幅度地下降以获得高效率。

NEWYORKER: The Tweaker

James Watt invented the modern steam engine, doubling the efficiency of the engines that had come before.

NEWYORKER: The Tweaker

The efficiency of his design is further improved by using the moving piston to drive water through a special steam nozzle, which increases the effectiveness of the heat transfer between the inside and outside of the reactor.
