摘　　要：针对句容市淡竹的主要理化性能和纤维形态进行了较为详细的试验,以求为后续小径级竹细观力学研究以及综合利用提供理论依据。结果表明:淡竹基部、中部、梢部平均壁厚及外径分别是4.03mm、3.05 mm、2.91 mm和33.16 mm、19.27 mm、12.07 mm;基本密度分别为0.53 g·cm-3、0.64 g·cm-3、0.73 g·cm-3;纤维长宽比为112.98;壁腔比为3.16;纤维组织比量、基本组织比量、输导组织比量分别为32.21%、58.73%、8.72%;化学成分中,灰分3.01%,二氧化硅0.18%;pH值5.68,总缓冲容量0.874 mmol。This paper studies the main physico-chemical properties and fiber morphology of Phyllostachys glauca. The aim is to provide a theoretical basis for the follow-up research on the utilization and micromechanics of small diameter bamboo. The results indicated that at the culm base,middle and tip,the average wall thickness and external diameter were 4. 03 mm,3. 05mm,2. 91 mm and 33. 16 mm,19. 27 mm,12. 07 mm respectively,the basic density were0. 53 g·cm- 3,0. 64 g·cm- 3and 0. 73 g·cm- 3respectively. The fiber length-width ratio was 112. 98,and the wall cavity ratio was 3. 16. The fibrous tissue proportion,the basic tissue proportion and the conducting tissue proportion were 32. 21%,58. 73% and 8. 72%respectively. The ash and silica content were 3. 01% and 0. 18% respectively. The pH value was 5. 68,and the total buffering capacity was 0. 874 mmol.
