电阻材料是用来制作电阻仪器、测量仪表以及其它工业装置中电阻元件的基础材料。广义而言,凡是利用物质的固有电阻特性来制造不同功能元件的材料均称电阻材料,如制作发热体的电热材料,绕制标准电阻器的精密电阻材料以及制作力敏、热敏传感器的应变电阻材料和热敏电阻材料等。本文仅就国外仪器仪表用的精密电阻材料和传感器电阻材料的近期进展与动向作一简要叙述。
Resistive material is used to make resistance instruments, measuring instruments and other industrial devices in the resistive element of the basic material. Broadly speaking, all materials that make use of the inherent resistive properties of materials to make different functional components are called resistive materials, such as electric heating materials for heating elements, precision resistive materials for standard resistors and strain gauges for making temperature sensitive sensors and thermosensitive sensors Resistance materials and thermistor materials. This article only a brief description of the recent progress and trends of precision resistance materials and sensor resistance materials used in foreign instruments and meters.
