摘要
用光导纤维和热电偶2种方法分别测得5种石墨管温度分布曲线,通过比较得到1种有近似时间及空间等温性的双管,它具有高灵敏度及强抗干扰能力.
The temperature distribution of different graphite tubes were measured withfiber optic and thermoeletricity. By comparison of the results, it shows that a tube-in-tubehas most homogeneous temperature distribution over others, therefore it has high sensitivityand high ability for the inhibition of interferences.
