Abstract

Abstract

The temperature distribution of different graphite tubes were measured with fiber optic and thermoeletricity. By comparison of the results, it shows that a tube-in-tube has most homogeneous temperature distribution over others, therefore it has high sensitivity and high ability for the inhibition of interferences.
