一、计算尺的构造原理任意 K 值视电阻率计算尺的构造与普通计算尺的构造相仿(图1)。整个尺身分为二部分,有二个滑尺,上滑尺刻着ρ_K 尺(也作 K 尺),下滑尺刻着 A 尺,A尺和尺身上的 B 尺是一个二节对数型尺。ρ_K 尺则是一 First, the construction principle of the slide rule Any K value apparent resistivity slide rule structure similar to the structure of the ordinary slide rule (Figure 1). The whole ruler is divided into two parts, there are two sliding rulers, the upper sliding ruler is engraved with ρ_K ruler (also known as K ruler), the lower ruler is inscribed with a ruler, the A ruler and the ruler B ruler is a two logarithmic ruler . ρ_K feet is one
