It is shown that the mean value of EMSR/GPa is 3.45% (0.56 GPa), which is greater than ES. Statistical linear regression analyses indicate that a relationship exists among dynamic and static elastic properties (at the significance level of 0.01), with a correlation coefficient of 0.9423 between EMSR and ES. Therefore, it may be concluded that the MSR technique can be used as an effective tool to predict static properties of full-size structural lumber. In addition, with a high degree of automation and the advantage of continuous batch detection, the MSR technique is very suitable for industrial applications today. So, a wide application of the mechanical stress grading technology in wood processing enterprises is surely possible., authors=null, authorsList=null, authorCompany=null, correspAuthors=null,

articleAbstract=运用日本产机械应力分等机，对384根足尺天然林落叶松锯材进行动态弹性模量EMSR测定，然后依据美国标准ASTM D 4761-05，测量其静态抗弯弹性模量ES，分析EMSR与ES的相关性。试验结果显示，机械应力分等法得到的动态弹性模量EMSR的平均值比静态抗弯弹性模量ES的平均值高3.45%（0.56GPa）；动态弹性模量EMSR与静态抗弯弹性模量ES具有良好的相关性，相关系数为0.9423，且在0.01水平显著。该研究表明，机械应力分等法可作为快速准确评价足尺结构用材力学性质的有效方法。,
