【摘要】 昆虫在壁画表面运动与附着时,会对壁画表面产生破坏。本文研究了仿爱夜蛾在敦煌莫高窟模拟壁画表面的附着力。仿爱夜蛾在壁画表面附着时,首先产生一定的法向抓附力,才能获得较大的切向摩擦力,保证其能够稳定附着于壁画表面。其脚爪对壁画表面的最大划力可以达到身体重力的15倍,从而造成壁画表面的细微划痕甚至引起起甲壁画的脱落。更多还原

【Abstract】 Out of concern that insects might destroy the murals as they move and burrow into the mural surfaces, this paper measures the adhesive forces of the Noctuid Apopestes spectrum on simulated murals in the Mogao Grottoes. In order to adhere stably to the mural surfaces, Apopestes spectrum produce a normal grip force before exerting a large tangential friction force. The maximum scratching force on the surface of the mural was about fifteen times the body weight of the insect, which might cause micro-scratches on the murals or even surface flaking.更多还原
