The technique worksbecause when water evaporates at sea, a combination of hydrogen and oxygenisotopes rise to form a cloud, which then releases rain when it moves inland.
这项技术的确有效，因为当水从海中蒸发后，氢和氧的同位素升起形成云，接着当它飘至陆地上空时再变为雨。
The technique works because when water evaporates at sea, a combination of hydrogen and oxygen isotopes rise to form a cloud, which then releases rain when it moves inland.
这项技术很有效，因为当水从海里蒸发，氢和氧的同位素组合升空形成云，接着飘至陆地上空降雨。
But the scientists note that their technique might also be used to prevent rain, by creating more of the smaller water droplets that stay airborne.
但是科学家指出，这项技术也许能将更多的小水滴停留在空气中从而阻止降雨。
