提出了量子混沌系统避免交叉概率分布的随机矩阵理论方法。分析结果得到的所有三个（正交，酉，辛）的普遍性类的物理系统，以及部分打破时间反演不变性的系统。对踢顶模型的数值试验结果与理论预测吻合得很好
The random-matrix-theory approach to the avoided-crossings probability distribution for quantum chaotic systems is proposed. Analytical results are obtained for all three (orthogonal, unitary, and symplectic) universality classes of physical systems as well as for systems with partially broken time-reversal invariance. The numerical experiments on the kicked-top model give results in excellent agreement with the theoretical predictions
