在晶体中存在位错、包裹体、沉积物，沉积到和微包裹体缀饰的生长条纹；
There are dislocations, inclusions, precipitates, row of precipitates as well as growth horizons decorated by microinclusions in the crystals.
分析比较了各类包裹物在晶体中的结晶方位，提出并证实了晶体中的有规则状包裹物具有明显的负晶结构特征。
BBO crystal has three types ofinclusions, which are disorderly floccose inclusion, the negative-crystal structure ditrigonal pyramid and prismatic inclusions.
高温下CaF2的挥发造成了在晶体生长后期熔体中组分偏离化学计量比，出现组分过冷，形成包裹物。
The volatilization of CaF2 at a high temperature causes the deviation in composition from the stoichiometry, which results in the formation of inclusions and an increase in the dislocation density.
