摘要：

A fivefold quasi-crystalline structure in a liquid has been obtained with five ultrasonic beams coming together in water according to a regular pentagonal array. A pressure scanning by means of a hydrophone probe has been made to show in a direct way the evidence of the quasi-crystalline pressure structure. Acousto-optic diffraction experiments by using a laser beam have also been performed.
