  • spectrum : n. （pl. -tra ）1. 【物理學】譜，光譜；波譜；能譜，質譜。2. 【無線電】射頻頻譜；無線電（信號）頻譜。3. 【心理學】（眼睛的）余像；殘像。4. 〈轉義〉范圍，幅度；（連續的）系列。
  1. The entropy or number of states of system or subsystem are closely related to interaction of particles and energy level distribution, therefore, to study the temperature dependence of the specific heat may supply some important and useful microscopic information which may play an important role in understanding electronic structure, density of state, phonon spectrum etc. the specific heat measurements at low temperatures also play important roles in the finding of the third law of thermodynamics, the quantum theory of solid and bcs theory for superconducting etc. moreover, specific heat measurements help us to understand the different kinds of phase transitions ( such as : structural phase transition, magnetic phase transition, superconducting phase transition etc. ) and the scaling behavior near the critical point

    系統、子系統的熵或微觀狀態數與微觀粒子間的相互作用及能級分佈密切相關，因此研究比熱與溫度的依賴關系能夠提供被測量系統許多極其有用的微觀信息，對理解固體的電子結構、電子態密度、聲子譜等起著十分重要的作用。低溫比熱的測量和研究對熱力學第三定律、固體量子理論和超導bcs等理論的建立起到了積極的推動作用。比熱研究還有助於認識各類相變如結構相變，磁性相變，超導相變等及臨界點附近的標度規律。
  2. At the same time, we show that under a proper nitrogen doping concentration, due to the " concentration quenching " effect, the full spectrum of the nn3 center ( i. e., its zero phonon line and various phonon replicas ) is revealed without the interference from the spectra of other higher energy centers ( especially nn4 - nn6 )

    Gapi . xn :的發光譜在低組分下由尖銳的nn 。線及其聲子伴線組成，隨著組分x的提高，這些尖銳的的譜線逐漸展寬，並向低能端移動，在這個過程中，激子的能量傳輸起著重要作用
