我国冰雪工作者在1980年以前大都使用铜电阻测量冰川温度。铜电阻具有正的温度系数,其温度每变化1℃,阻值的变化为0.4—0.6％。冰川测温用铜电阻由于体积的限制,一般阻值制做成300Ω左右,用它进行深冰川钻孔测温或远距离测温就有一定困难,必须采取一些措施来补偿由于引线电阻而带来的误差。同时铜电阻存在反应速度慢,加工复杂,成本高等缺点。
Most of the ice workers in our country used the copper resistance to measure the glacier temperature before 1980. Copper resistance has a positive temperature coefficient, the temperature change of 1 ℃, the resistance changes of 0.4-0.6%. Because of the limitation of the volume, the general resistance value of the copper resistance for glacier temperature measurement is about 300Ω. Using it for deep borehole temperature measurement or long-distance temperature measurement has some difficulties. Some measures must be taken to compensate for the lead resistance To the error. Copper resistance at the same time there is a reaction slow, complex processing, high cost shortcomings.
