双线摆 meaning in Chinese

bifilar pendulum

On the basis of this , a new designing plan is given in which problems of dimensional movement of a double lines pendulum and the method of its controlling have been involved
在方案中首先涉及到双线摆的空间摆动与控制问题，因此本文从分析动力学入手，建立了双线摆的运动微分方程。
Because the equation has a strong coupling and nonlinear form , it is hard to find out a resolution . then we simplify a double lines pendulum to a spherical pendulum model and set up its mathematical model
由于它具有强耦合性和强非线性，很难求出解析解，因此又将双线摆模型进一步简化成为球面摆模型，并建立了相应的数学模型。
