摘要

The claws of a house mouse (Mus musculus) and a yellow mouse (Citellus dauricus) and the foreclaws of a mole cricket (Giyllotalpidae) were examined with a stereoscope, a scanning electron microscope and a measuring microscope. It was found that these claws displayed a curved cone or pyramidal configuration. Both the upper outlines and the lower outlines of the claws had a complicated changing curvature. The curvature variation of the upper outlines was represented approximately by two parabolic segments and the curvature of the second segment was lower than the first segment for the claws of the house mouse and the yellow mouse. The curvature was least near the tips of each claw for all three animals. The curvature variation of the upper outline of the foreclaws of the mole cricket had two parabolic variations and a further increasing variation after the second parabolic segment. The lower outlines of the claws of the house mouse, the yellow mouse and the mote cricket were of one parabolic segment of the curvature variation and followed by one parabolic variation for the house mouse and a semi-parabolic variation for the yellow mouse and the mole cricket. The potential biomimetic engineering applications were discussed for the curvature-varyingfeatures of the claws of soil-burrowing animals in the design of soil-engaging components.
