    “Flicker frequency”是一个技术性术语,主要用于描述光源或显示设备的闪烁特性。以下是详细解释:

    一、词汇分解

    1. Flicker(闪烁)

      • 动词:指光源、火焰等快速且不规律地明暗交替,例如“The candle flame flickered in the breeze”(烛光在微风中摇曳)。
      • 名词:表示这种明暗交替的现象,如“the flicker of a screen”(屏幕的闪烁)。
      • 延伸义:也可描述情感或动作的短暂出现,如“a flicker of hope”(一线希望)。
    2. Frequency(频率)

      • 基本定义:指单位时间内事件重复的次数,单位为赫兹(Hz)。例如,广播频率“100 MHz”。
      • 技术应用:在物理学中用于描述声波、光波的振动次数,在数据分析中可统计数值分布(如Excel的FREQUENCY函数)。

    二、组合含义

    Flicker frequency 指光源或显示设备中光线明暗交替的频率,即每秒闪烁的次数。例如:

    三、应用场景

    1. 显示技术:高刷新率屏幕(如120Hz)能降低闪烁感,提升视觉舒适度。
    2. 照明设计:LED灯具需控制电流波动以避免频闪,防止视觉疲劳。
    3. 视觉研究:CFF测试可用于评估视觉疲劳或神经系统疾病。
