本文研究了正方形和三角形晶格中铁磁键和反铁磁键权重不对称的Ising自旋玻璃几何团簇的逾渗性质。通过MonteCarlo模拟，得到了渗流转变温度随铁磁键重的变化关系相图。在每个相变温度下，我们估计了临界指数ν和γ，它们与属于无规键逾渗普适类的指数（除了纯铁磁情况）吻合得很好。
The percolation properties of geometrical clusters are investigated for the Ising spin glasses in the square and triangular lattices with the asymmetric weights of ferromagnetic and antiferomagnetic bonds. By Monte Carlo simulation, we obtain the phase diagram of the percolation transition temperature as a function of the weight of ferromagnetic bonds. At each transition temperature, we estimate the critical exponents ν and γ which agree well with those exponents belonging to the universality class of the random bond percolation except for the pure ferromagnetic case.
