After logarithm fetch on minimum of viscosity, which get linear relation with pre-annealed temperature.
粘度极小值取对数之后与预退火温度成线性关系。
The higher the annealed temperature and the longer the annealed time, the stronger the new diffraction peaks.
随退火温度的升高和保温时间的增长，新衍射峰增强；
The position and strength of the peak are affected by the annealed temperature and that seems to be to related to kinds and density of defects.
结合激发谱对相应的激发与发光中心进行了讨论。 另外，还研究了退火温度对其峰位与峰强的影响。
