The meteoroid input function (MIF) describes the seasonal, diurnal and planetographic distribution of incoming meteoroids onto an atmosphere and/or surface of a solar system body. Utilizing state-of-the-art dynamical models of the main populations of meteoroids, we present a comparative study of the MIF on the atmospheres of Venus, Earth and Mars. Our modeling results show that, although a planet's axial tilt and orbital eccentricity introduce measurable important variability of the overall MIF, excursions from the ecliptic plane due to orbital inclination are responsible for the largest differences, producing variations of up to 40% with respect to the mean value in the overall mass fluxes of Venus and Mars. This is particularly true for meteoroid populations concentrated around the ecliptic plane, which are believed to be the dominant source of organics and metals on the atmospheres of these planets.

金星，地球和火星上层大气中类陨石的季节，时间和空间分布的比较建模研究

流星体输入函数（MIF）描述了进入的流星体在太阳系物体的大气和/或表面上的季节性，昼夜和行星分布。利用最新的流星体主要种群的动力学模型，我们对金星，地球和火星大气上的MIF进行了比较研究。我们的建模结果表明，尽管行星的轴向倾斜和轨道偏心率会引起整个MIF的可测量的重要变化，但由于轨道倾角而引起的黄道面偏移是造成最大差异的原因，相对于行星的最大偏差会产生40％的变化。金星和火星整体质量通量的平均值。对于聚集在黄道平面周围的流星类种群尤其如此，
