When their stems were cut, the plants started "screaming" between 20 and 100 kilohertz, and the scientists guess that this scream is probably meant to warn other plants nearby.
当它们的茎被切断时，这些植物开始发出20到100千赫兹的“尖叫”，科学家们猜测这种尖叫可能是为了警告附近的其他植物。
Up until recently, this was accomplished by accelerating the clock speed, which has leaped from kilohertz to gigahertz in my lifetime.
直至最近，这种状况都是靠提高时钟频率达到的，在我有生之年，我已看到处理器主频从几千赫兹上升至几吉赫兹。
