The investigators concluded that decreased ROM for the HRA group was attributed to a smaller head-neck ratio or head-neck offset at points of impingement.
研究者推断HRA组活动度降低归因于一个微小的头-颈比率或者头-颈在碰撞点偏移。

First we calibrate the accelerometers on dividing head to get the offset and sensitivity, then do the rotation experiments on centrifugal machine and rotating floor.
首先在分度头上标定加速度计，得到其零点和灵敏度，然后分别在离心机和转台上进行转速实验。

The paper introduces the concept of curve following turnout branch line, the confirmation of head and end, the chord offset calculation of points, the measuring steps in the field.
