凸起体 meaning in Chinese

asperity

Based on the direct shear test of double - asperity joints include two tooth - shaped asperities , the shear properties of double - asperity joints are analyzed according to the difference of two asperities ' angles , and the failure mechanism of double - asperity joints and the effects to joints ' failure mode and shear strength produced by the order of two asperities are discussed
摘要通过对由两个齿形凸体组合构成的双齿节理进行直剪试验，分析了两个齿形凸体的起伏角相等时和不等时双齿节理的剪切特性；观察和分析含两种不同起伏角凸起体的双齿节理的渐进破坏过程与机理，以及两个齿形凸起体的排列顺序对此类双齿节理的剪切强度和变形特性的影响。
