摘要:
In the described instrument ten‐microsecond, 30‐Mc carrier pulses reflected from a resonant layer allow a theoretical precision of 0.1 percent in making velocity determinations while using less than 0.1 cc of test liquid. By the same technique, ultrasonic absorption can be measured in highly dissipative liquids using layers about 0.1 mm thick. Water velocities observed at 30 Mc are presented along with values by others in the range of 0° to 93°C.V = 1554−0.0305(68.4−T)2is proposed as the best empirical parabola to accommodate the available data, and an additional cubic correction formula is suggested.
