摘要:
The method of ultrasonic interferometer has often been used in measuring the sound velocity in liquids. The accuracy of this method, however, is not an excellent. The present method will give a good advance in the accuracy and in the upper limit of the applicable frequencies. The writer was able to detect 0.2 μ of the movement in the acoustical path of particular distances. A frequency of 15 Mc was used.
