讨论了单体和群体林木种子对不同材料的静摩擦系数的测定方法。提出用无底盒装种子。填加种子工作厚度等效重量砝码．模拟堆集种子，测定群体种子摩擦系数，并介绍了测定仪的结构原理。利用倾斜法原理，测得６种树种、７种摩擦材料、９个平板的静摩擦系数，其结果胶合板为最好。
The methods for determining the static friction coefficient of different materials by monomer and group tree seeds are discussed. Proposed with bottomed boxed seed. Add seed work weight equivalent weight. The seeds were simulated and the coefficient of friction of population seeds was determined. The principle of the structure of the analyzer was also introduced. Using the principle of tilt method, the static friction coefficient of 6 kinds of tree species, 7 kinds of friction materials and 9 plates was measured. The result showed that plywood was the best.
