A、<strong style="line-height: 33px; white-space: normal;"><span style="font-family: 宋体;">热电偶在测比较低的温度时输出的热电动势太小</span></strong>
B、<strong style="line-height: 33px; white-space: normal;"><span style="font-family: 宋体;">铜电阻的阻值基本与被测温度呈线性关系</span></strong>
C、<strong style="line-height: 33px; white-space: normal;"><span style="font-family: 宋体;">热电偶测得的热电动势与被测温度呈线性关系</span></strong>
D、<strong style="line-height: 33px; white-space: normal;"><span style="font-family: 宋体;">热电阻测温一般采用三线制接法</span></strong>
