摘要：在借鉴已有理论，特别是Rose等的实验结果的基础上，通过对倾斜管道中固体颗粒加速运动的受力分析，详细描述了颗粒的运动状态和受力情况。最后运用数值分析中的曲线拟合原理得出了倾斜管道中附加阻力系数φ(θ)θ之间的函数关系。所得到的函数关系有较大的实践指导意义。

Abstract：In view of some available theories，especially of the result of Rose‘s research，this paper，by analyzing the movement of accelerated grains in the inclining pipeline，described the state of their movement and that of their bearing forces in detail.In the end，it deduced the functional connection between φ(θ) and θ through applying the principle of fitting curve to mathematic analysis.The function connection obtained will be of great significance of guidance to practice.
Key words：moving state ；extra coefficient of resistance；function connection
