组合量块定等及不确定度分析安徽省计量测试研究所黄秀丽１９９５年２月１日颁布实施了量块新的规程《ＪＧ１４６——９４》，量块分１等～６等，００级～３级。不同等级的量块用于不同精度的测量对象，选用过高或过低等级的量块都是不合理的。那么组合量块的等是如何确定...
The analysis of combined gauge block determination and uncertainty The Anhui Institute of Metrology and Measurement, Huang Xiuli, promulgated and implemented a new procedure for the gauge block “JG146-94” on February 1, 1995. The gauge block is divided into 1 equal to 6 and so on. ~3 level. Different grades of gauge blocks are used for measuring objects of different precision. It is unreasonable to select high or low grade gauge blocks. So how do you determine the size of a combination block?
