根据本发明，不需要取向膜，就能制备稳定的垂面取向液晶膜。
According to the present invention, regardless of the alignment film, a stable homeotropic alignment liquid crystal film may be manufactured.
结果表明：经等径角轧制后的板材，晶粒取向由等径角轧制前的(0002)基面取向演化为基面与非基面共存的取向。
It is found that the orientation of the sheet processed by ECAR is changed and the crystal orientation evolves from (0002) basal plane orientation to coexistence of basal plane and non-basal plane.
采用速率敏感晶体塑性理论，预测了面心立方金属板材单轴拉伸过程中主要理想取向的稳定性。
Orientation stability during uniaxial tension of face-centered cubic (FCC) metal sheets is predicted using a rate-sensitive crystal plasticity model.
