低温比热 meaning in English
low temperature specific heat
Examples
- Research in low - temperature magnetic behavior caused by superexchange interactions among transition metal ions in various compounds , including the experimental measurement of magnetic susceptibility and specific heat
研究领域:过渡金属离子化合物之合成与磁性研究,包括低温磁化率与低温比热之量测。 - The measuring of low - temperature specific heat is an important and effective method to study the structure of electronic states , the atomic vibration of lattice , phase transition and structure of grain boundary
低温比热测量是研究固体的电子能态结构、原子点阵振动状态、相变、界面结构等信息的重要的且很有效的手段之一。 - Because the lattice vibration is weak at very low temperature , the contributions of electrics and other low energy excitations become dominant parts of specific heat . therefore , we can study the micromechanism of many physical phenomena from specific heat measurement
在很低的温度下,由于晶格振动变得很弱,电子和低能激发贡献越来越突出,这对我们通过低温比热研究很多现象的微观机制十分有利。 - 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
系统、子系统的熵或微观状态数与微观粒子间的相互作用及能级分布密切相关,因此研究比热与温度的依赖关系能够提供被测量系统许多极其有用的微观信息,对理解固体的电子结构、电子态密度、声子谱等起着十分重要的作用。低温比热的测量和研究对热力学第三定律、固体量子理论和超导bcs等理论的建立起到了积极的推动作用。比热研究还有助于认识各类相变如结构相变,磁性相变,超导相变等及临界点附近的标度规律。
