摘要:
在非平衡直流电桥测量非线性电阻的基础上, 提出了恒流源非平衡直流电桥的概念, 推导了公式。与一般非平衡直流电 桥相比较, 采用恒流源非平衡直流电桥测量非线性电阻, 它的测量方法比较简单, 可以进行线性化处理, 提高了测量精度。采 用这一电桥对2.7 kΩMF11 型非线性电阻作了测量。方法是非线性电阻放在空气加热炉中并与一热容量较大的铜块紧密接触, 温控精度为0.1 ℃, 温控范围为室温～ 100 ℃。测量结果与理论结果相一致。
Abstract:
On the basis of measurement of nonlinear resistance with an unbalanced DC bridge , the concept of unbalanced DC bridge w ith a constant current bat tery w as proposed and the relevant formula of measuring nonlinear resistance was deduced .In comparison w ith the conventional unbalanced DC bridge , the method of measurement was quite simple by using the unbalanced DC bridge with a constant current battery .Furthermore linear processing could be made , and the precision of measurement could be increased .To measure resistance : (model 2.7 kΩMF11).The nonlinear resistance w as placed in an air -heating stove and in close contact w ith a copper bulk of larger heat capacity .The precision of temperature -controlling was 0.1 ℃, and the range of temperature controlling was from room temperature to 100 ℃.The measurement result was in accordance w ith the theory .
