The resulting scaling relationships are combined with an approximate bond moving scheme to treat pure and dilute models in higher dimensionalities.</p> <p>Detailed discussions are given for the dependence of correlation lengths and susceptibilities on temperature, anisotropy and concentration, and fcr the critical temperature on anisotropy and concentration.</p> <p>Particular emphasis is given to the weakly anisotropic system near percolation threshold and comparisons are made between the results of the present analysis and those of neutron-scattering experiments on dilute quasi-two- and three-dimensional systems.</p>
