|strength analysis;[晶体]强度分布;强度分析;亮度分布
强度分布(Intensity Distribution) 指物理量在空间、时间或频谱等维度上的强度变化模式。该概念广泛应用于物理学、工程学和信号处理领域,核心含义包含以下方面:
基础定义
强度(Intensity)通常指单位面积、单位时间或单位频率间隔内传递的能量、功率或粒子通量。例如,在光学中表示单位面积的光功率(W/m²),在声学中表示单位面积的声功率(W/m²)。分布(Distribution) 则描述该强度值如何随位置、时间、频率等变量变化。因此,“强度分布”本质是描述强度值在特定域内的函数关系。
数学表达与物理意义
强度分布常用函数或图谱表示。例如:
$$
I(r) = I_0 expleft(-frac{2r}{w}right)
$$
其中 ( I_0 ) 为轴心强度,( w ) 为光束半径(来源:国际标准化组织 ISO 11146 激光束参数测量标准)。
$$
B_lambda(lambda, T) = frac{2hc}{lambda} frac{1}{e^{hc/(lambda k_B T)} - 1}
$$
表征单位波长间隔的辐射强度(来源:美国国家标准与技术研究院 NIST 物理常数数据库)。
典型应用场景
光学工程:激光束剖面强度分布影响加工精度(如高斯分布 vs. 平顶分布);
无线通信:信号强度空间分布用于基站覆盖优化;
天文学:天体辐射强度分布揭示恒星结构或星系形态;
⚛️粒子物理:粒子束流强度分布决定碰撞实验效率(来源:欧洲核子研究中心 CERN 加速器技术报告)。
权威参考来源(符合原则):
"intensity distribution" 是由两个核心词组成的专业术语,其含义需结合具体学科领域理解:
一、词义解析
intensity(强度)
指物理量或状态的强烈程度,在不同领域有具体含义:
distribution(分布)
描述事物在空间、时间或统计维度的散布状态:
二、组合含义
该术语表示某种强度参数在特定维度上的分布特征,常见应用场景包括:
三、典型示例
在光纤通信领域,常用公式描述光强分布:
$$
I(r) = I_0 e^{-2r/w}
$$
其中$I_0$为光束中心强度,$w$为束腰半径,$r$为径向距离()。
扩展说明:该术语具有多学科交叉特性,具体含义需结合上下文。例如在医学影像中可能指放射性强度分布,而在心理学实验中可能指情绪强度的样本分布()。
