分析了自旋轨道耦合和塞曼分裂相互作用对横向半导体量子点弱局域化和普适电导波动的影响，列出了相应随机矩阵理论的所有可能的对称类，并描述了通过扫磁场和改变点参数可以实现它们之间的交叉。我们还提出了测量自旋轨道耦合常数的实验。
The effects of interplay between spin-orbit coupling and Zeeman splitting on weak localization and universal conductance fluctuations in lateral semiconductor quantum dots are analyzed: All possible symmetry classes of corresponding random matrix theories are listed and crossovers between them achievable by sweeping magnetic field and changing the dot parameters are described. We also suggest experiments to measure the spin-orbit coupling constants.
