摘　　要：介绍了PSD位置传感器的检测原理和一种基于PSD的钢丝杨氏弹性模量测量系统。实验结果表明,利用该系统可精确地测得杨氏模量,并且能定性地分析出钢丝在恒定外力(砝码)作用下的变化过程。The measuring principle of sensor PSD is introduced and the system for measuring Young modulus that is based on PSD is described in this paper .The result of the experiment shows that the Young modulus can be accurately measured by the system .The metabolic process of steel wire at unvarying outside force effect is qualitatively analyzed.

关 键 词：PSD 位置传感器 杨氏弹性模量 钢丝
