这个材质网络用一个表达式连接到螺纹去驱动螺纹的置换和一个渐变，去防止螺纹在顶端出现和在螺纹尖部出现。

The shading network connected to thread USES an expression to drive the displacement threading and a ramp to prevent the threading from appearing on the head and the tip of the screw.

螺纹材质网络是一个好例子，它证明了如何通过一个 数学表达式来驱动置换，它强于一个方便的纹理贴图。

The Screw Thread shading network is a good example of how displacement can be driven by a mathematical expression rather than a conventional texture map.
