据《new sientist》91卷1263期报导,澳大利亚 John Milburn 教授发现当植物缺水时,会产生一种噪声。研究得知,植物内部细微的输水脉胳的振动产生了这种噪声,发出“卡搭”“卡搭”的声响。这位教授把微型传声器放在植物茎部,“偷听”到了这种声音。利用这一技术可以用来测量新植物 According to “new sientist” Vol. 91, No. 1263, Professor John Milburn of Australia found that when a plant is dry, it produces a noise. Studies have shown that the vibration of the tiny water-feeding veins in the plant produces this noise and gives rise to the sound of “snap-in” and “snap-in”. The professor placed the microphones in the stems of plants and “eavesdropped” on the sound. The use of this technology can be used to measure new plants
