这样，才有可能分别导出两类弹簧支承(竖向的和扭转的)的刚度计算公式。
Thus, the calculative formula of rigidity for two spring bearings (vertical and torsional) may be obtained separately.
再检查车辆后面，看看车辆尾部是否有明显的损坏、开裂，是否有与悬挂装置或弹簧有关的零部件缺失，或者是否有漏油漏水一类的现象出现。
Move to the rear of the vehicle, while moving to the rear of the vehicles look for any obvious damage, broken or missing parts relating to the suspension, springs and any leaking fluids.
