摘　　要：从电阻丝的构造出发,利用均匀电阻丝中电阻大小与长度成正比这一特性,将所要测量的位置长度这一物理量转换为电阻的变化,从而制成了一维位置传感器。在实际实验教学中,为了进一步提高学生对位置传感器的理解,为了使学生在实验中真正把握、提高和拓展其灵活应用能力和与实践结合的能力,将简单的一位电阻位置传感器推广为二维电阻位置传感器。It showed the structure and characteristic of resistance wire that is the long of resistance wire the large resistance.If the length of resistance wire is measured,the location of moved point would be measured.This is the principle of one-dimension resistance-location sensor.In practice,we use two resistance wires to structure two-dimension resistance-location sensors,it makes the students capability to apply and capability to understand would be increased.
