Gibbs thomson公式
WebGibbs-Thomson I: The density. On the basis of the aforementioned claims, we can already state a version of the Gibbs-Thomson formula for the difference of densities “due to the presence of a curved interface.” Indeed, since the droplet only accounts for a fraction, λ 1, of the excess particles, the remainder (1 − λ 1)(ρ ‘ Web一般而言，我们可以将MH算法推广到多维的场景下，并加以应用。. 不过在这里，我们将介绍一种 应用更为广泛 的多维分布抽样方法—— 吉布斯抽样（Gibbs Sampling）。. 吉布斯抽样的思想非常简单且直观，而它与Metropolis-Hasting算法也存在着千丝万缕的联系。. 如 ...
