Bell不等式的失败根源和对定域性原则的直接检验

On the Cause of Bell Inequality Fail and Direct Test of Locality Principle

本文考查了各种Bell不等式的理论推导和实验检验方法,分析了不等式失败的原因,指出:双值自旋粒子系、严格的关联条件和定域性原则都是导致Bell型不等式与实验相悖的可能因素。以往的检验实验不足以否定定域性原则。为了单独地直接检验定域性原则,文中提出了一个新型不等式。

Various methods of theoretical inference and experimental test of Bellinequality are investigated. The cause of inequality fail is also anllysed. Itis pointed out that the two-valued spin system, strict correlation conditionand locality principle are all possible factors causing conflict between Bellinequality and experimental results. Former experiments are not sufficientto negate locality principle. A new inequality is suggested to test localityprinciple directly.
