在35°K附近，玻璃二氧化硅的内摩擦达到峰值，随频率增加而增加。扭转和杨氏模量的温度曲线在65°K附近呈向上凹形，且与频率无关。这些影响随温度的变化而可逆。它们的原因不可能是通常类型的松弛过程或任何涉及扩散或大量剪切的过程。
Near 35°K the internal friction of vitreous silica reaches a peak value which increases with frequency. The temperature curves of the torsion and Young's moduli are concave upward with minima near 65°K and are independent of frequency. These effects are reversible with temperature. Their cause cannot be the usual type of relaxation process or anything involving diffusion or large amounts of shear.
