图3. 一个周期内鱼体的姿态变化图. 鱼体内色彩深度表示主动弯矩绝对值的大小,鱼体两侧的虚线分别表示 正曲率(红色为 $0 \pm 0.3\pi$ 相位区)和负曲率(蓝色为$\pi\pm 0.3\pi$相位区)
Fig. 3. Locomotion of fish body during one swimming cycle. Color intensity on the body indicates the absolute value of active bending moment. The dashed lines near the two sides of body indicate positive and negative curvature regions
