| Abstract: | This artical researches into the vibration of a cantilever rectangular platein the linearly distributed stable-temperature fields -with the time-average holography. Its natural freguencies and models of the vibration are obtained in different and linearly distributed stable-temperature fields. The experimental results show that when an object is vibrating in the stable-temperature field, not only the natural freguencies but also the models of vibration will be changed as compared wih that in normal temperature. |
