下潜

The experimental results prove that an IPMC based centimeter scale micro robot fish is feasible. The velocity control can be realized by changing frequency and duty ratio of the control signal, and ascent-descent, turning, cruising can be realized by the cooperation of pectoral fin and caudal fin.

实验结果证明，基于IPMC的厘米级机器鱼是可行的：通过改变控制信号的频率和占空比，实现微型机器鱼的速度控制；通过控制胸鳍和尾鳍，实现上浮、下潜、转弯、巡游等运动模式。

Apart from anything else, we just loved the clean but always extended and tuneful bass this setting gave, with an utterly convincing sense of timing that made the most of the rhythmic qualities of any musical style.
