大气密度大气密度atmospheric density daqi midu大气密度(atmospherie density)单位体积大气中含有的空气质量或分子数目。前者称质量密度(简称密度)，单位为千克每立方米;后者称分子的数密度，单位为米一3。大气密度又称空气密度。大气质量密度取决于气温、气压和空气湿度，通常不是直接侧得，而是经计算求出的。其数值随高度按指数律递减。海平面高度的大气密度标准值为1.2250千克每立方米。 大气密度是决定物体在大气层中运动时所受空气动力大小的主要因素之一，对在空气中飞行的各种飞行器有重要影响。大气密度及其分布也是影响波在大气中传播的重要因素之一，如密度的变化，可使声波、无线电波、光波在大气中的传播路径发生折射，改变传播方向。(史余山)
