This review describes and demonstrates the Q-space analysis of light scattering by particles. This analysis involves plotting the scattered intensity versus the scattering wave vector q=(4 pi/lambda)sin(theta/2) on a double log plot. The analysis uncovers power law descriptions of the scattering ...
我试图使用scipy.stats.pareto定义一个Pareto发行版,但是我使用的模型是一种完全不同的形式,它有三个参数,其中有f(x) = (gamma(alpha + k) * lambda**alpha * x**(k - 1)) / (gamma(alpha) * gamma(k) * (lambda + x)**(alpha + k))。我还尝试设置k = 1,以便将分布简化为两个参数 浏览0...
