 This brilliant step separates the position vector into parts that depend only on the nodal DOFs and the lengthwise coordinate $\zeta$ (the $\mathbf{r}_{o,x,y}$ vectors), and parts that depend on the cross-section coordinates ($x, y$). This is the key that unlocks the integration in the next stage.

 最终目标是找到叶片中任何质点的位置矢量 $\mathbf{r}$，因为所有惯性力都由此导出（参见式 1.8）。
