【摘要】 本文提出唯象的玻色型元激发模型,成功地解释低温下(<1K)玻璃的某些反常热力学行为:比热-温度的非线性关系,声速与温度的InT规律,并预测热膨胀系数仍保持为负值.更多还原

【Abstract】 A phenomenological model of Bose elementary excitations is proposed to explain the anomalous thermal properties of glasses at low temperatures (<1 K), namely, the nonlinear temperature dependence of the specific heat, the temperature In T law of the sound velocity. Wealso predict a negative thermal expansion between 0-1 K.更多还原
