分别求下列两个向量的内积, 并判断是否正交, 若没有正交, 请利用施密特正交化过程将其化成规范正交向量组.
(1) $\alpha_1=\left(\begin{array}{l}1 \\ 0 \\ 1\end{array}\right), \alpha_2=\left(\begin{array}{c}1 \\ 1 \\ -1\end{array}\right)$
(2) $\alpha_1=\left(\begin{array}{l}2 \\ 1 \\ 0\end{array}\right), \alpha_2=\left(\begin{array}{l}0 \\ 1 \\ 0\end{array}\right)$
