摘　　要：万能激光测长机是一种可以进行绝对测量和相对测量的长度计量仪器,用途非常广泛。量块检定一般采用比较法测量,对于非标准长量块的测量现在可以利用万能激光测长机进行测量。介绍了用万能激光测长机测量非标准长量块的方法,并对其不确定度进行了详细分析。The multi-purpose laser measuring machine is one kind of length measuring instruments which can be used to take measurement relatively and absolutely, it is widely used in geometrical quantity measurement. In general, the gauge block measurement is certified by comparison,but for the non-standard long gauge block,it may be certified with the machine. In this article ,the author introduce a new measuring method for the non-standard long gauge block with the multi-purpose laser measuring machine,and analyze its uncertainty in detail.
