dimension invariant的用法和樣例：
例句
- Since scalars are independent of the coordinate system, the dot product of two vectors is called a scalar invariant.
因為標量與坐標系無關，故兩個矢量的點積稱為標量不變數。 - The invariant eigen-operator method is successfully applied to solving energy levels for some quantum systems Hamiltonian.
摘要目前不變數本徵算符方法已成功地解決了某些量子系統哈密頓量能級問題。
