据报道，熔融石英平板长期变形的案例。这种现象是在纳米尺度上检测到的，并且表现出 9 年量级的时间常数。观察到的变形似乎与重力和约束有关，但也假设局部物理特性的变化导致非相似行为。
Cases of long-term deformation of fused silica flats are reported. The phenomenon is detected at the scale of the nanometer, and exhibits a time constant of the order of 9 years. The observed deformation appears related to gravity and constraints, but a change of physical properties locally resulting in non-homothetic behavior is also hypothesized.
