行为学家克拉特曾做过一个实验:在水池中心放入一只小白鼠。虽然水面很大,但仍在小白鼠游泳能力所及的范围之内。小白鼠落水后没有急于游动,而是一边转圈,一边发出吱吱的叫声。原来,它是在利用鼠须测定方位。叫声传到水池边沿,声波反射回来,被鼠须测到,水池大小、自己所在的位置、离池 Behavioral scientist Krat had done an experiment: put a mouse in the center of the pool. Although the surface is very large, but still within the scope of mouse swimming ability. After the mouse fell into the water is not eager to swim, but while circling, while squeaky creaking. It turned out that it is in the use of rat whiskers to determine the orientation. Called to the pool edge, the sound wave reflected back, measured by the mouse must be, the size of the pool, where you are, from the pool
