摘要:采用应力波技术对胡杨树干进行检测,探讨古树名木快速检测与评价方法。结果表明,通过健康树干断面波速传播趋势及函数关系,可对缺陷树干健康状况进行诊断,但对边部开裂无法准确诊断。波速与检测角度存在二项式函数关系。
Stress wave equipment was used to detect defects in olive tree stems(Populus euphratica).Results showed the equipment could quickly diagnose tree trunks' decay,but could not accurately detect surface cracks in tree stems.A binomial formula was used to develop a relationship between velocity and transmission angle.The formula alone,with the velocity pattern from a healthy tree trunk cross-section,could be used to diagnoses the defects in a tree trunk.
