| 摘 要： | Based on the theory of the pulsed photoacoustic signal in liquid generated by a pulsed laser, a novel, optically noncontact, fast and accurate method for temperature-dependent ultrasonic velocities for ethanol and water has been demonstrated. The experiment results are in good agreement with literature values.
