Are elementary particles point-like objects?
摘要：
基于不确定原理和狄拉克方程的简单论证表明，电子的行为要么是点状电荷，要么是扩展分布，这取决于高能或低能实验。
英文摘要：
Simple arguments based on uncertainty principle and Dirac's equation are examined which show that electron behaves either as a point-like charge or as an extended distribution according as high- or low-energy experiments are considered.
