1·Normal rolling sheets have obvious preferred grain orientation and basal plane (0002) is parallel to the rolling plane.

常规轧制板材具有明显的晶粒择优取向，大部分晶粒的(0002)基面都平行于轧板表面。

2·A 25.12 centimetres of the column basal plane circumference, is high 24 centimetres, cuts it into a maximal cone, cuts cubic centimeter volume number going to.

一个圆柱的底面周长25.12厘米，高24厘米，把它切成一个最大的圆锥，切去的体积多少立方厘米。

3·The electrochemical characteristics of carbon atoms on the edge and basal plane were determined by analyzing structure of graphite crystal and bond of different carbon atoms.

分析了石墨微晶结构与成键特征，研究了石墨微晶中边缘碳原子与基平面碳原子的电化学特性。

4·The utility model has the advantages that the verticality of the axial lead of the electric drill and a basal plane is good, and the machining precision of drilling holes is high.

该磁座钻的电钻轴心线与基面垂直度好，钻孔加工精度高，有很好的推广应用前景。

5·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.

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。
