The common conclusion was the uniqueness and necessity of euclidean geometry . 欧几里德几何的唯一性与必要性已被公认。
The non-euclidena geometries were in effect subordinated to euclidean geometry . 非欧几里德几何实际上是从属于欧几里德几何的。
The euclidean norm of an n-vector x with real or complex components is defined as following . 凡具实数分量或复数分量的n-维向量x的欧氏范数被定义如下。
Science should always try to use euclidean geometry and vary the laws of physics where necessary . 科学应该永远试用欧几里德几何学,并在必要处改变物理定律。
We prefer the form (5.16.7) since it is in conformity with the definition of scalar product in a complex euclidean space . 我们愿意用(5.16.7)这种形式,因为它和复欧几里德空间中标积之定义相谐调。
