得到了横场作用下无限程伊辛自旋玻璃的复制对称破缺解。在不采用静态近似的情况下，在第一步RSB计算了淬火自由能和玻璃化转变温度与横向场的相边界。我们证明，副本对称性（RS）必须打破自旋玻璃相通过比较的RSB和RS解决方案的自由能。没有发现证据支持中间自旋玻璃相与副本对称性
The replica-symmetry-breaking (RSB) solution of the infinite-range Ising spin glass in the presence of a transverse field is obtained. The quenched free energy and the phase boundary of the glass transition temperature versus the transverse field are calculated at first-step RSB without using the static approximation. We demonstrate that replica symmetry (RS) has to be broken in the spin-glass phase by comparing the free energies of the RSB and RS solutions. No evidence is found to support an intermediate spin-glass phase with replica symmetry
