竹子是壁薄中空的圆锥体,个体间尺寸差异较大,不同尺寸、不同材性的竹子混用会降低竹材利用率,为了使材料各尽其用,对于竹秆尺寸和圆竹分级的研究是必要的。笔者调查了浙江新昌毛竹竹秆的秆形参数和圆竹的尺寸参数,包括竹秆的胸径、枝下径、枝下高、全竹高、圆竹的壁厚、围径等,并计算尖削度。结果发现:竹秆的胸径与枝下高、全高、枝下径等具有较好相关性,并以胸径为竹秆的分级指标,以0.5 cm为分级模数,将竹秆分为9级,其中胸径9.5～11.5 cm为主径级区。对圆竹的尺寸进行统计得到,以1 m为截断长度时,以壁厚为分级指标,第Ⅰ段圆竹的壁厚较多为11 mm,第Ⅱ和第Ⅲ段以9 mm居多,第Ⅳ段以8 mm为主,第Ⅴ...

Bamboo has been used for many applications, from a food source to structure and building materials. Many manufacturers have seen all the products that can be made from this highly renewable resource and have begun to utilize bamboo in numerous creative ways. Bamboo is a hollow cone cylinder with thin wall and the size of bamboo varies greatly among individuals. Mixing use of bamboo with different sizes and properties will reduce the utilization rate of bamboo. In order to make the best use of bamboo materials,it is necessary to investigate the size distribution of bamboo pole and the classific...
