Rayleigh scattering , named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering particle (normal dispersion regime), the amount of scattering is inver… Web百度百科是一部内容开放、自由的网络百科全书，旨在创造一个涵盖所有领域知识，服务所有互联网用户的中文知识性百科全书。在这里你可以参与词条编辑，分享贡献你的知识。

Consider the two-dimensional vector $${\displaystyle Y=(U,V)}$$ which has components that are bivariate normally distributed, centered at zero, and independent. Then $${\displaystyle U}$$ and $${\displaystyle V}$$ have density functions $${\displaystyle f_{U}(x;\sigma )=f_{V}(x;\sigma )={\frac … See more In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom. … See more The probability density function of the Rayleigh distribution is $${\displaystyle f(x;\sigma )={\frac {x}{\sigma ^{2}}}e^{-x^{2}/(2\sigma ^{2})},\quad x\geq 0,}$$ where $${\displaystyle \sigma }$$ is the scale parameter of … See more • $${\displaystyle R\sim \mathrm {Rayleigh} (\sigma )}$$ is Rayleigh distributed if $${\displaystyle R={\sqrt {X^{2}+Y^{2}}}}$$, … See more • Circular error probable • Rayleigh fading • Rayleigh mixture distribution • Rice distribution See more The raw moments are given by: $${\displaystyle \mu _{j}=\sigma ^{j}2^{j/2}\,\Gamma \left(1+{\frac {j}{2}}\right),}$$ See more Given a random variate U drawn from the uniform distribution in the interval (0, 1), then the variate $${\displaystyle X=\sigma {\sqrt {-2\ln U}}\,}$$ has a Rayleigh distribution with parameter See more An application of the estimation of σ can be found in magnetic resonance imaging (MRI). As MRI images are recorded as complex images but most often viewed as magnitude images, … See more WebThe Rayleigh ratio (R q) is defined as the relative scattering intensity or the ratio of scattered (I s) to incident (I o) light, with the strict definition requiring that the scattering intensity be … WebApr 9, 2015 · 财务比率（Financial Ratios）财务比率是财务报表上两个数据之间的比率，这些比率涉及企业管理的各个方面。财务比率(financial ratio)可以分为四类：变现能力比率](liquidity ratios)]、资产管理比率](activity ratios)]、负债比率](debt ratios]和盈利能力比率](profitability ratios)]。 impressive grouping crossword
