iterative - 迭代

Iteration means the act of repeating a process usually with the aim of approaching a desired goal or target or result. Each repetition of the process is also called an "iteration", and the results of one iteration are used as the starting point for the next iteration.
In the program, it can said to be the loop.

迭代通常是指行為重複的過程，目的是接近理想的目標或結果。每個重複的過程也稱為“循環”，一個迭代結果是作為下一次迭代的出發點。
在程式上,可以說是執行回圈。
