磅秤
Based on the steel truss bridge mode of 1 ∶ 10 scale, the identification methods of bridge structure damage detection was discussed. By finite element method and hammer pound method with Varied-Time-Base ( VTB) technology, the modal test analysis of bridge modal was done.
本文以1∶10钢桁架桥梁模型为研究对象,用有限元模型及实验模型进行局部损伤的识别,实验采用锤击法及变时基(VTB)技术对桥梁模型进行了模态分析。
In this scale there are sixteen ounces to the pound.
这种秤每磅是16英两.
If you put on another a pound weight the scale can be balanced.
如果你再放上一个一磅的砝码,这个秤就能平衡.
