摘要：

The precise ultrasonic experiment was performed on the single crystal La2(1-x)Sr2xCuO4. Longitudinal sound waves of 200 MHz were propagated along and perpendicular to c-axis. Sound velocity exhibits jump DELTA-v/v almost-equal-to 4 x 10(-5) at T(c) for the case along c-axis, whereas DELTA-v/v less-than-or-equal-to 4 x 10(-6) for perpendicular to c-axis.
