摘要
The concept of excessive mesons in nuclei is discussed.Since nucleons are identical particles,it is pointed out that the physical content of a meson distribution around a bound nucleon in nuclei is different from that of a meson clotid around a free nucleon,if the effect of the principle of identity cannot be neglected.The difference is enunciated in detail.
