高度发展仪器制造业的准确度要求,需要更多地用干涉测量法进行长度测量。对于微电子工业技术方面的仪器要求采用波长不确定度高达1×10~(-8)的波长标准。为此,东德标准化计量与产品检验局必须具有这种波长标准和相应的测量方法,其不确定度不得超过1×10~(-9)。这一要求将通过国际努力被确认,以促成不久以后长度单位米的新定义,新定义将会符合未来年代里所提出的要求。
Highly demanding accuracy requirements for instrumentation manufacturing require more length measurements using interferometry. For the technical requirements of the microelectronics industry using wavelength uncertainty of up to 1 × 10 ~ (-8) wavelength standard. To this end, the East German Standardization Measurement and Product Inspection Bureau must have this wavelength standard and the corresponding measurement method, the uncertainty of not more than 1 × 10 -9. This requirement will be confirmed through international efforts to bring about a new definition of unit length in the near future and the new definition will meet the requirements set forth in the coming years.
