摘　　要：烧杯的固有频率可以用直接测量法、共振法或水滴流调制法加以测定，各法中均利用利萨如图形．测定过程中学生在教师引导下运用已学到的知识去克服遇到的困难，于是。The intrinsic frequency of a beaker can be determined by means of direct determination,resonance or water drip modulation,and each of the methods makes use of the Lissajous' figure.During the process of determination, the students need to be guided to apply related knowledge they gained to remove obstacles occurred,thus their ability can be improved.

关 键 词：烧杯 固有频率 利萨如图形 频率测量 相位
