| 摘 要： | 蚯蚓体表的形状是蚯蚓适应其生存环境和自然进化的结果．用力学分析方法，解释蚯蚓的多体节非光滑形态在其运动过程中所表现出的省力、节省能量的特性．计算结果表明具有波纹形表面的蚯蚓在蠕动过程中可以节省1．12%的纵向肌肉的收缩力，在运动过程中所消耗的能量也可以节省1％左右． |
| 关 键 词： | 蚯蚓 蠕动 非光滑形态 体表力学 能量节省 |

| Abstract: | It is the result of natural evolution that an earthworm with a multi-sectional non-smooth wavy surface can perfectly adapt its living environment. An earthworm moving in soil needs less longitudinal muscle contract force and less energy than those required to move a similar sized cylindrical body. The computational analysis shows that such an earthworm body with the wavy surface can reduce its muscle contract force by 1.12%, and a similar amount of energy as well. |
| Keywords: | earthworm creeping non-smooth surface |
