维基百科公式不显示怎么办 找不到latex公式怎么办？

一劳永逸 维基百科公式不显示怎么办？

1. 注册1个wiki账号，
2. 参数设置,
3. 显示选项卡，最后的PNG图片点上；
   成功；

2 粗一点 or 找不到latex公式真么办？

不想注册账号？ 拷贝wiki原文，放入latex解析功能的文档中；比如CSDN （$前后空格全部替换掉)；如下：

A Rician fading channel can be described by two parameters:$K$Kand$\Omega$Ω.[1]$K$Kis the ratio between the power in the direct path and the power in the other, scattered, paths.[2]$\Omega$Ωis the total power from both paths ($\Omega =\nu ^{2}+2\sigma ^{2}$Ω=ν2+2σ2), and acts as a scaling factor to the distribution.

The received signal amplitude (not the received signal power)$R$Ris then Rice distributed with parameters$\nu ^{2}={\frac {K}{1+K}}\Omega$ν2=1+KK​Ωand$\sigma ^{2}={\frac {\Omega }{2(1+K)}}$σ2=2(1+K)Ω​.[3] The resulting PDF then is:

$f(x)={\frac {2(K+1)x}{\Omega }}\exp \left(-K-{\frac {(K+1)x^{2}}{\Omega }}\right)I_{0}\left(2{\sqrt {\frac {K(K+1)}{\Omega }}}x\right),$f(x)=Ω2(K+1)x​exp(−K−Ω(K+1)x2​)I0​(2ΩK(K+1)​​x),
where$I_{0}(\cdot )$I0​(⋅)is the 0th order modified Bessel function of the first kind.

latex写论文的小伙伴有福了，果断抄抄，高大上 糙猛快，既能装逼又能深入理解数学大厦；
