风速矢端图直观的显示了风场随高度的切变情况，相对风暴螺旋度则在数字上表明了对流风暴的发展强度，螺旋度越大，强对流天气越可能发生。

Wind vector map shows the wind shear condition with height intuitively , and storm-relative helicity shows the intensity of convective storm development in figures . The greater the helicity is the more likely severe convective weather will occur .

设计人员按设计意图对各曲线段指定其上各点处的目标法矢分量比率图，比较目标法矢分量比率图与实际法矢分量比率图，即可判断出各曲线段的光顺性。

According to the design intent , target normal vector ratio plots of these segements , which are provided by the designer , are compared to actual normal vector ratio plots , so the smoothness of every curve segment can be identified .

由于样品淬火后晶片装饰在织构上而不影响分子取向矢的分布，因而可以用化学刻蚀和电镜技术揭示其向错和取向矢图。

Because the distribution of molecular director was not affected by lamellar decorating after quench , chemical etching and SEM technique were used to reveal disclination and director patterns .
