1. Shear force is implicit in the development of bending moments. 杆中的剪力在弯矩的推导中是不明显的。
2. The bending angle increases with an increase of the energy density. 增加能量密度，板料的弯曲角度显著增大。
3. The bending radius reduces with increasing length of the mainstream line, and then tends to be relatively stable. 随主流线长度增加，弯曲半径不会无限制减小，将会趋于某一相对稳定状态；
