摘　　要：用应力波非破损检测技术检测中密度纤维板弹性模量的研究（续）王志同，曹志强，袁卫国（中国林科院木材工业研究所北京１０００９１）２试验方法与步骤本试验所用的中密度纤维板试材主要从市场购买。这些试材由北至黑龙江省南至广东省的五个省、市的六家工厂生产的。这些...Studies on exact measuring methods of stress wave velocity with modern electron-ic technology;the relationship among modules of elasticity with density and stress wave ve-locity of materials tested;the correlativity between stress wave and destructive testing ac-cording to relevant Chinese National Standard in force were conducted.The research resultsindicated that the bending modules of elasticity measured by non-destructive testing of stresswave was precise enough and it was possible to develop online quality control system of MDFaccording to mechanical properties and automatic control system of production line.
