Before the pocket calculator, every engineer computed on a slide rule: logarithmic C, D, A, K and L scales engraved on a celluloid or bamboo body, read through a glass cursor and its single hairline. This system borrows that instrument's grammar — parallel scale bands, fine graduated ticks, a sliding register — and dresses it in Pickett's vivid Eye-Saver Yellow with crisp black engraving. It is precision made visible: nothing decorative, everything measured.
在袖珍计算器出现之前，每个工程师都靠计算尺运算：对数 C、D、A、K、L 各刻度 雕在赛璐珞或竹身上，透过玻璃游标与那道发丝般的细线读数。本系统借用这件仪器的 语法——平行的刻度带、细密的刻线、滑动的标尺寄存器——并披上 Pickett 那抹鲜亮的 护眼黄，配以利落的黑色刻印。这是把精密变得可见：没有一处是装饰，每一处都在度量。
