摘　　要：按照国家标准GB/T 1927-2009采集处理样本,借助光学显微镜和扫描电镜,分别从宏观角度和微观角度研究了皂荚木材的解剖构造;利用木材万能力学试验机,参照现行国家标准对皂荚木材的力学性质进行了测试和分析。结果表明:皂荚木材属于环孔材;轴向薄壁组织丰富,傍管环管束状;木射线纺锤形,多为同型多列。皂荚木材气干密度为0.774g/cm^(3)。皂荚木材硬度(端面、径面、弦面)、顺纹抗压强度、顺纹抗拉强度、抗弯强度和抗弯弹性模量分别为:9364 N、7876 N、8356 N、54.02 MPa、145.44 MPa、125.44 MPa、9784 MPa,综合评价为高档用材。Samples were collected and processed according to the national standard GB/T 1927-2009,the anatomical structure of Honey-locust wood was studied from the macroscopic and microscopic perspectives by means of optical microscope and scanning electron microscope,and the mechanical properties of Honey-locust wood were determined and analyzed by means of the universal mechanical testing machine of wood and referring to the current national standard.The results showed that:Honey-locust wood belongs to ring hole wood;there are more axial thin-walled tissues,which are round tube bundles;the ray spindle shape of wood,which are mostly of the same type and many rows.The air dry density of Honey-locust wood was 0.774g/cm^(3).The hardness of Honey-locust wood is 9364N,7876N,8356N,54.02MPa,145.44MPa,125.44MPa and 9784MPa,the wood belongs to high-grade timber.
