The fastener incorporates two or three loosely wound loosely wound thread-cutting blade-like helical projections (5) extending radially from a solid axialcore (2).
该紧固件具有两个或三个切削松卷螺纹的刀状突起(5)，该刀状突起从实心的中轴(2)向外放射状延伸。

Fiber tension can be reflected indirectly by measuring axial tension. Therefore the acquisition and processing of axial tension is the core part of fiber tension test.
光纤拉力可以通过测量轴向拉力来反映，因此轴向拉力数据的采集和处理是光纤拉力测试的核心部分。
