摘　　要：直接测量岩石表面降低的高度是研究当前地表侵蚀速率的有效方法。本文介绍了一种新型可直接进行岩石侵蚀速率测量的仪器—便携式高精度游标螺旋测微装置的组成和原理,并利用该装置在北京延庆地区进行了野外实地测量。本次测量共获得1920个数据,其数据平均偏差和标准偏差均小于1μm,表明该装置在1μm数量级精密度稳定且良好,说明该装置在野外直接测量岩石侵蚀速率方面具有可行性。Directly measuring the height of the rock surface reduction is an effective method to study the current rate of surface erosion.This paper introduces the composition and principle of a portable high-precision vernier helical micrometer,a newly developed instrument that can directly measure rock erosion rates,and uses the improved device to conduct field measurements in Yanqing,Beijing.A total of 1920 measurement data were obtained this time,and the average deviation and standard deviation of the data were both less than 1μm,indicating that the precision of the device in the order of 1μm was stable and good,and the device is feasible in the field to directly measure the rock erosion rate.
