高精度细丝直径测量系统的不确定度

Uncertainty in high accuracy thin wire measurement system

详尽分析了ＶＤＭ—Ｉ型高精度细丝直径测量系统中影响测量不确定度的各种因素，将其分为Ａ类和Ｂ类评定的不确定度分别讨论，最终将其合成，得到该系统的标准不确定度。

The influence factor of uncertainty in VDM-I high accuracy thinwire measurement is studied. Type A and type B uncertainty of measruement beseparately discussed and finally combined into standard uncertainty of the measurement system.
