impedance ratio meaning in Chinese

阻抗比

Abstract : from the equilibrium and continuity conditions of wave impedance boundary of stress wave and velocity , wave , the paper derives the expressions of reflection coefficient and transmission coefficient of stress wave and velocity wave , further , discusses the characteristics of f - v curves at different impedance ratio , and analyzes the application of these characteristics to ascertain the defects of pile and soil resistance distribution around pile by practical engineering examples
文摘:该文从力波及速度波在波阻抗界面的平衡及连续条件，推导了力波、速度波的反射系数、透射系数表达式，进而讨论在不同阻抗比时的f ? v曲线特征，并引用几个工程实例对应用这些特征判定桩身缺陷及桩周土的阻力分布进行了分析。
