热力学第三定律 meaning in English
third law of thermodynamics
third principle of thermodynamics
Examples
- The third law of thermodynamics
热力学第三定律 - 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。
