摘　　要：[目的]更加精确地表征甘蔗茎外皮的机械特性。[方法]将传统拉伸试验与像素分析法相结合,测算出不同组别甘蔗茎外皮试件的拉伸强度及弹性模量,进而进行对比分析。[结果]研究表明,4组试件的拉伸强度整体呈下降趋势,经碱处理不带有甘蔗节的试件的拉伸强度最高,而未经碱处理带有甘蔗节的试件,其拉伸强度相对微弱;较带有甘蔗节的试件而言,不带甘蔗节的试件的弹性模量相对较大。[结论]综合来看,碱处理可在一定程度上提高甘蔗皮的机械性能;甘蔗节对甘蔗皮机械特性有所影响,但影响较小。[Objective] In order to characterize the mechanical properties of sugarcane rind more accurately.[Method] Combined traditional tensile test and pixel analysis method,the tensile strength and elastic modulus of sugarcane rind specimens was measured.And then a comparative analysis was conducted.[Result] The results showed that the tensile strength of four groups of specimens is on a decline curve.The tensile strength of the sugarcane rind without joints that treated with alkali is the highest.Without alkali treatment,the tensile strength of sugarcane rind with joints is relatively poorer.Compared with the specimens with joints,the elastic modulus of sugarcane rind without joints is relatively large.[Conclusion] Taken together,alkali treatment can improve the mechanical performance of the sugarcane rind to a certain degree,and the joints has an less effect on the mechanical properties of the sugarcane rind.
