摘　　要：树蛙的足掌趾指端均带有椭圆形的吸盘。依靠吸盘所产生的吸附力,树蛙攀爬行走在竖直的墙面上。采用扫描电镜和原子力显微镜研究了中国大树蛙的吸盘微观结构,利用三维力学测试系统对中国大树蛙进行足掌接触力学性能测试,并用高速摄像同步跟踪拍摄其步态行走状况,分析其接触力的变化规律。The treefrog possesses toe pads with ellipse in shape, which enables the treefrog to adhere to the vertical wail. The microstructure of adhesive discs for the China big treefrog is studied by the scanning electron microscope and the atomic force microscope. By the application of the 3D-force sensor system and the high speed video camera, the adhesive capability of the treefrog about mechanfcs is measured, and the status of action is recorded. The status of contact forces of the toe pads is analysed during the locomotion of tree frog.
