种子的悬浮速度是反映种子空气动力学特性的一个参数,它对于设计和使用种子风选机,种子气力输送装置等种子机械有很大意义。迄今国内对于树木种子的悬浮速度还未进行过系统的研究。本文在理论分析的基础上,利用实验的方法,对十五种树木种子的悬浮速度,及影响悬浮速度的因素进行了测定和分析。 Seed suspension velocity is a parameter that reflects the aerodynamic characteristics of the seed and is of great significance to the design and use of seed machinery such as seed-wind-picking machines and seed-pneumatic conveying devices. Up to now, no systematic research has been conducted on the seedling suspension speed in China. Based on the theoretical analysis, this paper used the experimental method to measure and analyze the suspension speed of fifteen tree seeds and the factors that affect the suspension speed.
