迭代指重复执行某个过程或步骤,常用于计算机编程、数学和日常生活中的反复操作。

用法要点

句型搭配

iteration 常与介词 of 连用,表示“...的迭代”,如 iteration of a process;也可与介词 in 连用,表示“在...中的迭代”,如 in each iteration。

• iteration of the algorithm
• in the next iteration
• multiple iterations

介词用法

iteration 常与介词 of 搭配,表示所属关系;与介词 in 搭配表示在某个过程中的迭代;与介词 through 搭配表示通过多次迭代完成某事。

• iteration of the design
• in the first iteration
• through several iterations

语域说明

iteration 在计算机科学和数学领域使用频率最高,属于正式用语;在日常对话中较少使用,多用于描述重复性工作或改进过程。

• software iteration
• iterative process
• design iteration

基础例句

常见错误

❌ 错误:We need to do an iteration for the project.
✓ 正确:We need to do an iteration of the project.

iteration 通常与介词 of 搭配表示“...的迭代”,而不是 for。正确表达是 iteration of something。

❌ 错误:This is the second iteration for this software.
✓ 正确:This is the second iteration of this software.

表示软件版本时,应使用 iteration of software,而不是 iteration for software。of 表示所属关系更准确。

近义词辨析

repetition

repetition 强调简单的重复动作,不涉及改进或变化;而 iteration 强调在重复过程中有改进、调整或演变的含义。

Repetition of the same task is boring. (简单重复) vs. Each iteration of the design improved its functionality. (改进性重复)

cycle

cycle 强调一个完整的循环过程,可能包含多个步骤;iteration 更强调单次重复执行的过程,通常作为循环中的一次。

The water cycle includes evaporation and precipitation. (完整循环) vs. We completed one iteration of the testing cycle. (循环中的一次)
