When testing, it is more likely for cold-rolled and twisted steel bar to be broken in fixture and so that its plasticity can hardly be precisely measured.
冷轧扭钢筋在检测时，试样易在夹具内断裂，其塑性难以精确测定。
By selecting test equipment and using high precision scaling device or precisely measuring the primary scale, an accurate testing of cold-rolled and twisted steel bar may be realized.
通过正确选择（或改进）测试设备和使用高精度刻标机或精确测量原始标距等手段，即可实现冷轧扭钢筋的正确检测。
