摘　　要：针对具有自旋轨道耦合的散射问题,通过对称性分析,给出了时间反演不变性条件下的散射矩阵的一些严格性质.特别对于二端问题,在导线为空间单模(导线本身也可以含自旋轨道耦合)的情况下,证明了其透射矩阵为常数乘以二维幺模幺正矩阵的形式.Based on symmetry analysis,some general properties of the scattering matrix of spin-orbit coupled system under the constraint of time reversal symmetry were presented. In particular,it was proved that in the two terminal problem with single-channel leads（ the conducting leads may have spin-orbit coupling on their own）,the transmission matrix was proportional to a matrix.
