在图1的装置中，液体能够从液面高的容器A通过导管不断流到液面低的容器B，这种现象叫做虹吸现象，液体流经的那根管子叫做虹吸管．使用时，首先将液体吸过管子的最高点F，再继续向下吸，当B容器的液面低干A容器的液面时，它便自动持续不断地将液体从A容器中吸到B容器里．虹吸 In the device of Fig. 1, the liquid can continuously flow from the container A with a high liquid level through the conduit to the container B with a low liquid level. This phenomenon is called the siphon phenomenon, and the tube through which the liquid flows is called a siphon tube. In use, first the liquid is sucked through the highest point F of the pipe, and then continues to suck downwards. When the liquid level of the B container lowers the liquid level of the A container, it automatically and continuously sucks the liquid from the A container to B. Container. Siphon
