目前四等量块的檢定,不仅是太原市各厂的一个急待解决的問題,而且也是全国較普遍存在的問題。因为检定四等量块需要超級光学計,而超級光学計是靠进口的供不应求,价錢昂贵。在此情况下把投影光学計或光学計改为0.00005毫米的投影光学計或光学計,对我們开展工作,是有重要意义的。計量工作1959年第二期“用光学計检定四等量块問題的探討”一文中揚永剛同志从理論上分析了光学計的精度并且实际上也証明了光学計仪器本身的誤差很小,足可以檢定四等量
At present, the verification of four equal blocks is not only an urgent issue to be solved by the factories in Taiyuan, but also a more prevalent problem throughout the country. Because the verification of the same amount of blocks requires super-optics, and super-optics rely on imports in short supply, the price is expensive. In this case, changing the projection optics or optics to 0.00005 mm projection optics or optics is of great importance to our work. Measurement of the second phase of 1959, “the use of optical test four equal block problem” in a paper Comrade Yang Yonggang theoretically analyzed the accuracy of the optical meter and in fact also proved that the error of the optical instrument itself is very small, full You can check four equal amounts
