将下列段落翻译 Flash steam stations pull deep, high- pressure hot water into lower-pressure tanks and use the resulting flashed steam to drive turbines. They require fluid temperatures of at least 180 °C( 292 °F ) ,usually more .This is the most common type of station in operation today .Flash steam plants use geothermal reserv oirs of water with temperatures greater than 182 °C( 360 °F ) .The hot water flows up through wells in the ground under its own pressure. As it flo ws up ward, the pressure decreases and some of the hot water boils into steam. The steam is then separated from the water and used to power a turbine or generator. Any leftover water and condensed steam may be injected back into the reservoir, making this a potentially sustainable resource. At the Geysers in California, twenty years of power production had depleted the groundwater and operations were substantially reduced. To restore some of the former capacity, water injection was developed.
