    “brightness temperature”(亮度温度)是一个物理学和遥感领域常用的术语,其含义及背景如下:

    一、定义

    亮度温度是指一个物体在特定波长或频率下,其辐射的亮度所对应的等效黑体温度。即使物体本身并非理想黑体,其辐射强度可通过黑体辐射公式转换为温度值,这一温度即称为亮度温度。

    二、核心概念

    1. 亮度(brightness)
      指物体表面的明暗程度或辐射强度,与光线的反射、发射特性相关。

      • 发音:/ˈbraɪtnəs/
      • 相关术语:高亮度(high brightness)、亮度控制(brightness control)。
    2. 温度(temperature)
      表示物体冷热程度的物理量,此处特指通过辐射能量推算的温度。

      • 发音:/ˈtemprətʃər/

    三、应用领域

    四、公式表示

    亮度温度可通过普朗克辐射定律计算:
    $$ B{ u}(T) = frac{2h u}{c} frac{1}{e^{h u/(kT)} - 1} $$
    其中,$B
    { u}(T)$为辐射亮度,$T$为亮度温度,$h$为普朗克常数,$k$为玻尔兹曼常数。

    五、与其他术语的关联

    如需进一步了解,(欧路词典)、(亮度温度翻译)及(亮温解释)。
