摘要
钢丝弹性模量测量导致产生测量误差的因素很多,其中有反射镜的摆放、反射镜后脚长度调整、反射镜望远镜和标尺高度的调整、钢丝长度的测量、钢架水平的调整等。详细分析了以上诸多因素对钢丝弹性模量测量产生误差的原因。
In the wire elastic modulus measurement there are many factors which can result in measure- menl errors： placing of reflector, reflector rear feel length adjustment, the adjustment of heights of re- flector, telescope and scale,wire＇s length measurement and steel frame level adjustment, etc. This pa- per aims to analyze why the above mentioned factors may cause the errors in the wire elastic modulus measurement.
