摘要
给出了T>TC和T<TC情况下不同能谱的n维简并理想玻色气体的内能及热容量的普遍表达式,应用于三维极端相对论理想玻色气体时则在T=TC处热容量CV出现跃变,这与通常玻色气体的CV在TC处连续的结果不同.
The general expressiones of energy and heat capacity of n-dimensional ideal Bose gas with differnet eneregy-momentum relations are obtained at temperature T>T C and T<T C .It is shown that the curve of heat capacity vs temperature is discontinuous at condensation temperature T C for 3 D extreme-relativeistic Bose gas,which is different from other Bose gases whose C V is continuous at T=T C .
