The cause of resulting in trembling mark in the tube drawing;
冷拔钢管抖纹产生的机理及消除方法
The mechanism of producing trembling marks of tube was analyzed by nonlinear dynamical system theory.
提出了锥形模短芯棒钢管拉拔的非线性动力学模型,利用非线性动力系统理论研究了钢管拉拔过程中抖纹产生的机理。
It is quite difficult to realize long-term stable quantum key distribution (QKD) with polarization encoding due to the effect of irregular polarization fluctuation in single mode fiber.
由于长距离单模光纤传输中存在的双折射效应会引起偏振随机抖动,光纤中利用偏振编码进行量子密钥分发一直难以实现。
