测定空气比热容比实验的探讨

With nicer specific stiffness, specific strength and higher heat resistance, titanium alloy is the key material for high performance aero-engine to reduce weight and improve thrust-to-weight ratio. Thus it is widely used in fan, compressor and other components of modern aero-engines.

钛合金具有良好的比刚度、比强度以及较高的耐热性能，是高性能发动机减轻结构重量、提高推重比不可或缺的关键材料，因而在现代航空发动机风扇、压气机及其它构件中得到了广泛应用[1-3]。

The Specific heat volum, heat conductivity, thermal diffusion ratio increase and linear expansion coefficient decrease with an increase of graphitization degree of pitch derived carbon.

随着沥青炭石墨化程度的增大，比热容、导热系数、热扩散率都增大，而线膨胀系数减小。
