摘要
设计了一套利用圆盘放大和普通长度测量工具相结合的测量微小长度的工具,分别利用该设计装置和螺旋测微器对钢丝的直径和普通A4纸张的厚度进行了测量。结果显示了新设计的可行性、创新性和数据的高精度性、准确性。
An instrument of measuring the minimum length has been designed using two disks and a commonly length measuring tool.The diameter of steel wire and the thickness of A4 sheet were measured respectively employing this experiment and the micrometer.The feasibility and the innovation were approved,the extraordinary precision and veracity were displayed.
