摘要 本文证明 ,在贝尔定理的证明过程中 ,实际上用到电子自旋 (或其他费米子的自旋 )的任意两个分量的联合概率 ,而这一联合概率却并不存在 ,因此 ,贝尔定理言之无物。贝尔的工作的意义是通过“自旋相关函数”的“隐变量表达式”或其他公式 ,在这种纯属子虚的联合概率与现实的跃迁概率之间建立一种人为的关系 ,并引出一个矛盾 ,从而证明这两种概率各自遵循不同的规律。这一工作既不涉及定域性原理也与经典概率论无关。 It is brought to light that a joint probability for two arbitrary projections of an electron spin (or another fermion's spin) is actually used in the Proof for Bell's theorem and this joint probability is fictitious, so that Bell's theorem is faulty. Also, the significance of Bell's work is established, with the aid of 'the hidden variable expression' of 'the spin correlation function' or another formula, an artificial relation between these unreal joint probabilities and the real transition probabilities, and finding a contradiction. As a result, it is revealed that these two kinds of probabilities obey different laws respectively. This work has nothing to do with locality nor with classical probabilities.
