A negative face has an outward normal pointing in a direction opposite that of the positive x-axis.

负向的外法线指向与正x轴相反的方向。

Here the normal map is applied to the low-detail model, and you can see how each channel encodes the surface information along each axis.

下图演示了将法线贴图附加在低分模型上，这里你可以看见各个分量分别为表面添加了那些附加的信息。

Light lateral and axis and torsion vibrations do not affect the normal work, but the resonance state has severity effect to drill string.

轻微的横向、轴向及扭转振动不影响钻井的正常作业，而钻柱的共振状态会对钻井产生严重的影响。

Along with the growth of age and body, optic axis gradually lengthens to the normal.

随着年龄及身体的增长，眼轴逐渐加长，至而渐趋正常。

The red channel in a normal map encodes the left-right axis of normal blue channel encodes vertical depth.

法线贴图中的红色通道编码了法线的左右轴，蓝色通道编码了垂直深度。
