| 摘 要： | FromEinstein’s supposition aboutcrystal lattice vi-bration, which states that the vibration frequency of ev-ery crystal lattice is the same, the balance of heat ener-gy in the crystal can be written out using the theory ofstatistical thermodynamics, so that the molar heat capac-ity under normal temperatures can be easily calculated.For many kinds of metals, the theoretical value of themolar heat capacity is close to the experimental value.In other kinds of metals, though, especially metals of… |
| 关 键 词： | Einstein’s solid model molar heat capacity nonlinear interaction coefficient of expansion |
