摘要：
In this paper we report the results of a small scale experiment (a 3 m long flume) to measure long waves of small to large amplitude at the interface of two non-miscible fluids (water and petrol). Ultrasonic (2 MHz) probes are used to measure the interface displacement. We discuss a fitting method to remove noise while preserving the highly nonlinear features of our data. We find very good agreements between inviscid theories and our experimental data.
