But communicating with a submarine (潜艇) or a diver is not so easy. The lack of practical methods for sharing data between underwater air
12、borne (空气传播的) devices has long been a frustration for scientists. The difficulty stems from the fact that radio signals work perfectly in air travel but poorly in water. Sonar (声呐) signals used by underwater sensors reflect off the surface of water rather than reaching the air.Now, researchers at MI
13、T have developed a method with the potential to revolutionize underwater communication. “What weve shown is that its actually feasible to communicate from underwater to the air, ” says Fadel Adib, a professor at MITs Media Lab, who led the research.The MIT researchers designed a system that uses an
14、underwater machine to send sonar signals to the surface, making vibrations (震动) corresponding to the 1s and os of the data. A surface receiver then reads and decodes these tiny vibrations. The researchers call the system TARF. It has any number of potential realworld uses, Adib says. It could be use
