|frictional coefficient;[力]摩擦系数；磨擦系数
摩擦系数（coefficient of friction）是物理学和工程学中描述两个接触表面之间摩擦力特性的重要参数。它表示两个物体相对运动时，摩擦力与垂直作用于接触面的法向力（即正压力）之间的比例关系，其数学表达式为：
$$ mu = frac{F_f}{N} $$
其中，$mu$为摩擦系数，$F_f$为摩擦力，$N$为法向力。该系数无量纲，且通常介于0到1之间，但某些特殊材料（如橡胶与金属的组合）可能超过1。
摩擦系数受材料性质、表面粗糙度、温度及润滑条件等影响。例如，金属与金属接触时若未润滑，摩擦系数较高（约0.5-0.8），而加入润滑油后可降至0.1以下。
在机械设计中，摩擦系数用于计算机械零件的磨损寿命（参考《University Physics》第15版）；在交通安全领域，轮胎与路面的摩擦系数直接影响制动距离（美国国家公路交通安全管理局相关研究）。
“Coefficient of friction”（摩擦系数）是描述两个接触表面之间摩擦力特性的物理量，通常用符号$mu$表示。以下是详细解释：
摩擦系数是摩擦力（$F_f$）与垂直于接触面的正压力（$N$）的比值，公式为： $$ mu = frac{F_f}{N} $$ 它是一个无量纲的标量值，没有单位。
若需更深入的计算或实验数据，建议参考物理学或工程力学教材。
