摘　　要：对木材细胞壁力学性质研究中零距离拉伸、单根纤维拉伸技术和纳米压痕技术进行概述,分别从滑移与夹持力、试样厚度和试样含水率评述零距拉伸技术,从纤维分离方法、纤维夹紧和定向、单根纤维细胞壁横截面面积测量评述单根纤维拉伸技术,从连续刚度测量法、针尖效应以及原子力显微镜与纳米压痕技术的联用评述纳米压痕技术。通过归纳、总结与展望,提出了该领域的研究重点,以期为木材细胞壁力学研究及其资源的高效利用提供借鉴。Advances in the researches of mechanical properties of wood cell were reviewed from the aspects of zero-span tensile, tensile of single fiber and nanoindentation respectively. The clamping force , moisture content of samples and thickness of samples were studied from zero-span tensile. Fiber separation, fiber clamping and orientation and measurements of single fiber cross-sectional area were reviewed from tensile of single fiber. Continuous stiffness method, tip of nanoindentation and union of AFM and nanoindentation were indicated from nanoindentation aspect.
