circular definition

基本解釋

A recursive definition is similar to a circular definition, in the sense that the definition contains a reference to the thing being defined.
遞歸定義與循環(huán)定義有些相似，就是函數的定義體內包含了對所定義內容的引用。一一個完全循環(huán)的定義并不會有太大用。
Through the example, we gave the pattern ask for the most value make a clever use of the definition of circular Cone bend line in this paper.
巧用圓錐曲線的定義，通過具體實例說明求最值的一些方法，對中學數學教學有積極的參考價值。
But this definition assumes that most planets have roughly circular orbits, like the Earth and most other planets in the solar system.
但這一定義的前提是，假定大多數行星以近乎圓形的軌道圍繞母星運行，就像地球和太陽系其他大部分行星那樣。

It looks like a circular definition right now.
這看起來像是循環(huán)定義了
