精密因瓦水准尺关键技术指标研究

RESEARCH ON SPECIFICATIONS OF PRECISE INVAR STAFF

研究了涉及因瓦水准尺生产、检定与使用中相关标准的一致性问题。研究发现:国内因瓦水准尺使用标准的技术指标与国外因瓦水准尺生产标准的技术指标存在较大差异,依据目前国内的使用标准无法判定因瓦水准尺是否满足生产标准。

The standard is the basis of a product for manufacture,calibration and use.The consistency of relevant standards which are applied in those fields of the invar staff is researched.The study demonstrates that the parameters in national standards for calibration and use are much different from those in international standards for manufacture.
