钓界有传说:硬尾浮漂的灵敏度比软尾的高。其一种解释,认为软尾是空心的,空心的浮力大,浮漂下顿时漂尾增加的浮力就大,阻力就大,所以灵敏度低;还有一种解释,认为硬尾较重,可帮助浮漂下顿,所以实心的灵敏度高,真是这样吗?根据阿基米德定律,一个物体所受液体的浮力只决定于它浸入到该液体中的体积,与物体的重量及物体内部的质量分布无关。例如体积相等,一个空心,一个实心的两个钢球浸没在水中,如图(1)所 Diaoyu Islands legend: hard tail float sensitivity than the soft tail. One explanation is that the soft tail is hollow, large hollow buoyancy, floating suddenly under the buoyancy increase on the large resistance large, so the sensitivity is low; there is an explanation that the hard tail heavy, can help float According to Archimedes’ law, the buoyancy of an object’s liquid depends only on the volume it plunges into the liquid, irrespective of the weight of the object and the mass distribution within the object . For example, equal volume, a hollow, a solid two steel balls immersed in the water, as shown in Figure (1)
