The method could be suitable for calculating the thrust and the normal force for other kinds of linear motors.

对此方法的可扩展性进行了讨论，指出此方法同样适合于其他类型直线电机的推力和垂直力计算。

The Failure model of slopes can be classified into 2 kinds, toppling model and sliding model. The force distribution of each model is analyzed in oblique coordinate system, and the equation to calculate the forces are derived. Many external forces, such as earthquake force, water pressure, bursting force, bolting force and etc., can be easily considered in these equations.

分析了倾倒模式和滑动模式两种岩质边坡的破坏型式，对其受力情况进行了分析，并利用刚体平衡理论，给出了在斜角坐标系下推力计算方程，该方程可以方便地考虑任意方向的地震力作用，还可以考虑水压力、锚固力、建筑物外荷载和其它人工作用力。
