Based on force diagram an analytical expression between some factors and splaying angle of the bar is brought forward, pointing out that splaying angle of the bar should be 2 3 degrees, and slitting angle should be 30 degrees approximately, outboard slant angle on the slitting groove should be 45 50 degrees and bite angle should be 7 8 degrees.

为稳定小规格带肋钢筋的三线切分轧制，对涉及棒材张开角的切分孔孔型诸角度进行了分析，通过对轧件受力状态的讨论，提出了诸因素与棒材张开角之间的解析式，指出满足三线切分稳定轧制时的棒材张开角应为 2°～ 3°，相应的孔型切分角为 30°左右，孔型外侧壁倾角应在 4 5°～ 5 0°之间，咬入角可控制在 7°～ 8°之间等。

Under the vertical load, the strength of rock mass is higher when there is only one group of joint and the dip angle is less than 20 or higher than 80; When dip angle is between 20 to 80, the strength of rock mass is much lower, it is smallest when dip angle is about 50, and it is lower when this kind of dip angle is in combination with other angle.

7在铅直向荷载作用下，岩体中只存在一组倾角小于20°或者大于80°时，岩体的强度相对较高；当岩体中存在一组节理的倾角在20°～80°间时，岩体的强度值很小，而且在与其他倾角的节理组合时，岩体的的强度值变化不太大，特别是当节理倾角为50°左右的时候，岩体的强度相对最低。

With a dip angle between 15° and 30°, the uplift of an obducted plate during continental collision is much higher, and able to form a high mountain. The uplift is greatest with a dip angle of 15°; whereas with a dip angle between 30° and 45°, the subduction depth of a plate is much deeper, and able to form a deep basin. The subduction depth is greatest with a dip angle of 45°. When the dip angle is equal to or greater than 75°, subduction and obduction movements between two continents become undistinguishable.
