摘要
研究表明,几何非光滑体表是土壤动物减粘降阻的原因之一。通过对典型土壤动物蜣螂的大量观察、实验研究和表面分析,发现其体表不同部位具有不同的几何非光滑;将土壤力学与生态学相结合,还探讨了在粘湿环境中蜣螂非光滑体表与不同触土方式的关系及其对防粘特性的作用机理。
The investigation has been shown that the geometric nonsmooth cuticle is one of the causes of soil animals for reducing adhesion and resistance. In this paper, through a great deal of observations, experiments and surface analysis of dung beetle, it has been discovered that the different parts of its cuticle possess different geometric nonsmooth surfaces. Combining soil mechanics and ecology, we discuss the relationship between nonsmooth cuticles of dung beetle, its different ways of touching soils, and its mechanism of reducing adhesion in the adhesive and wet environment.
