摘　　要：在JJG 146—2011《量块》检定规程中,根据量块长度的测量方法给出了被测量块在标准温度(20℃)时的长度偏差计算公式。本文对使用光波干涉仪直接测量小尺寸二等量块长度时,被测量块及其附近空气的温度变化对测量结果的影响进行了分析,探讨了使测量结果更加可靠的途径。In the verification regulation of JJG 146—2011 Gauge Blocks,the formula of how to calculate the length deviation at the standard temperature(20 ℃)based on the gauge blocks length measured method. In this paper,the influence of temperature changing by testing gauge blocks and air nearby are analysis when using optical interferometer detecting second class gauge blocks to make the results more reliable.
