摘要：

Three different algorithms are presented for Brownian Dynamics simulations of diffusion on the unit sphere restricted by the intersection with a symmetric or distorted cone. The second rank time correlation function K-2(t)=Sigma(n)[D-On(2)(theta(t), phi(t))D-*(On)2(theta(O), phi(O))] = [3[n(t)n(O)](2)-1]/2 has been determined. The three algorithms are compared and discussed with respect to computational efficiency and accuracy.
