等距的

The new type of rotary compressor has two key parts, an outer rotor and an inner one which employs isometric curve of trochoid as its profile.

从理论上分析了一内、外转子结构回转式压缩机,其内转子线由短幅外摆线内等距线构成。

These observations allow one to formalize the definition of reflection: a reflection is an involutive isometry of an Euclidean space whose set of fixed points is an affine subspace of codimension 1.

这些观察允许们形式化反定义: 反是欧几里得空间对合等距同构，它不动点集合是余维度为 1 子空间。
