| 摘 要： | 在借鉴已有成果，特别是许振良教授提出的水平管道固体粒子处于滑、跳移时的速度分布模型理论的基础上，结合底层固体颗粒的起动条件，运用数值逼近方法确定堆积速度的计算公式。最后用相关数据对这些公式进行检验，计算结果与实际测量结果较为符合。

| Abstract: | On the basis of the existing research results of experts and scholars,especially the theory put forward by Professor Xu Zhenliang on the model of velocity distribution when solid particles were in the condition of slip or jump in the horizontal pipeline, and by referring to the ground floor solid starting terms of particles, we got the formula of deposit velocity with a numerical approximation method. Finally, related data were used to verify the deprived formulae. And it turned out that calculation results accord with actual ones. |
