乌克兰共和国标准计量中心研制成一种高精度水平仪检定器,它是由普通的水平仪检定器装配上辅助平板和导板(图1),这样更便于用过去的方法测量角度。方法的实质见图2,图中表面 A 和 B 相当于平板的工作表面和安装水平仪检定器的平板的工作表面。直线 CD是平板和导板的工作表面的交叉线;角度α_0是用普通水平仪检定器形成的角度,而角度α_β=α_0cosβ (1)
The Ukrainian National Institute of Standards and Metrology has developed a high-precision calibrator, which is fitted with an auxiliary plate and guide plate (Figure 1) by an ordinary level calibrator, making it easier to measure angles in the past. The essence of the method is shown in Figure 2, where surfaces A and B correspond to the working surface of the slab and the working surface of the slab on which the spirit level gauge is mounted. The straight line CD is the intersecting line of the working surface of the plate and the guide plate; the angle α_0 is the angle formed by the ordinary level gauge and the angle α_β = α_0cosβ (1)
