Slide rheostat choosing to limite current or divide voltage by graph analysis

本文采用GPS定位、罗盘及滑动变阻器反馈、步进电机控制等数字化引导方式，便于实现，并可提高系统的可靠性和稳定性。

This paper proposed system bases on GPS positioning , compass and sliding rheostat feedback , stepper motor control and other digital guide way .

用数表及无感固定电阻取代传统冲击法测量中的电流表和滑动变阻器，大大减缩短了测量装置的接线，同时使测量装置更易于操作。

Analogue meters and potentiometers can be replaced by digital meters and non-inductive resistors in the classical ballistic method , so it makes wiring and operating more easier .

方法将压力传感器（本文采用YH24）与位移传感器（本文采用滑动变阻器）进行合理组装，使得压力与位移之间呈线性关系。

Method A pressure sensor ( YH-4 ) and a displacement sensor ( sliding rheostat ) were assembled into a probe so that they work in a linear mode .
