According to scale inspecting regulation, the author come up with a trial-and-error adjusting method based on the unequal character between calculated value of arm unequal error and actual adjusting value.
根据天平检定规程,利用检定值计算出的不等臂性误差与实际应调量不等,作者在实际经验的基础上,提出了试调法,利用天平的四个平衡位置计算出横梁不等臂性误差的应调量,大大提高了工效,更由于这个试调法无须先称量悬挂系统的质量,这对于大型天平的调修是比较方便的。

补充资料:放大镜
放大镜
magnifier
    用来观察物体细节的简单目视光学器件,是焦距比眼的明视距离小得多的会聚透镜。物体在人眼视网膜上所成像的大小正比于物对眼所张的角(视角)。视角愈大,像也愈大,愈能分辨物的细节。移近物体可增大视角,但受到眼睛调焦能力的限制。使用放大镜,令其紧靠眼睛,并把物放在它的焦点以内,成一正立虚像。放大镜的作用是放大视角。为作比较,物放在明视距离s0(250毫米)处,裸眼观察时的视角为j,用放大镜观察时,令虚像也位于明视距离处,视角变为j ′。定义视角放大率(或称放大倍数)为
