【摘要】 文章探讨了电阻车型仪器地层模型（刻度盒）的实物制作到计算机仿真设计的发展过程及详细的设计方法。利用电阻网络输入阻抗计算软件验证了由地层电模型简化为仪器刻度盒方法的正确性，澄清了仪器研制人员在仪器刻度盒设计中存在的一些模糊认识。同时，该软件还可以用于指导仪器研究人员的电路调试工作。更多还原

【Abstract】 The design principle of reisitivity logging tool’s calibration box is discussed in detail. A software is developed to calculate the pair-wise resistance of the calibration box and to simulate the working statue of resistivity logging tool. With the software, we can determine if each part of the calibration box is connected correctly. The software can also be used to simplify the design of calibration box and to aid the design of electrical circuits.更多还原
