采用焰熔法生长金红石单晶体时，有时发现在晶体中部生长有透明、半透明间杂的包裹体，且包裹体中有平行条纹．利用ＳＥＭ和ＸＲＤ对其（１１０）面分析研究发现，包裹体是由基本为（１１０）面取向的小晶体构成的多晶体，有的小晶体受到张应力作用，有的受到压应力作用；包裹体（１１０）面中的平行条纹为晶体的层错线或晶界，取向为［００１］，它形成于热应力造成的沿（１１０）面的解理．
The Transparent and semi-transparent mixed inclusion is sometime found in the rutile single crystal grown by flame fusion methods. Moreover, parallel
stripes are shown in the inclusion. By means of XRD and SEM, (110) face of crystal with inclusion was investigated. It is shown that inclusion is
polycrystal, which consists of (110) orientated small crystal grains, some of them are affected by tension stress, the others by pressure stress.
On the other hand, parallel stripes in inclusion are layer-dislocation lines or crystal boundaries, which orientate [001], they are formed from cleavage along (110) face
due to thermal stress.
