Meanwhile the pions quickly decay into mu mesons , or muons , which penetrate to the ground 同时，介子会快速衰变成缈子抵达地面。
" for his prediction of the existence of mesons on the basis of theoretical work on nuclear forces 提出核子的介子理论并预言介子的存在
Kaonic atom k 介子原子
Ideally , they would use muons but , in practice , they are using a close cousin , the pion 选用介子是最理想的，但在实验中使用的是与之很相似的介子。
The non - gaussian form of spatial distribution of source can lead to the decrease of the parameters 介子源空间分布的非高斯形是导致参数减少的一个重要因素。
Read chap . 5 of your text book to complement our discussion of heavy mesons in chiral perturbation theory 10阅读教材第五章以补充关于手征微扰理论中重介子的讨论。
" for his development of the photographic method of studying nuclear processes and his discoveries regarding mesons made with this method 发展研究核过程的照相方法，并发现介子
Meanwhile we find that decay constant fn and the tt mass mv monotonously decrease as nuclear matter density increases 我们同时发现介子的衰变常数f _和质量m _随着核物质密度_ n的增加而单调递减。
These effective coupling constants of mesons embody the feature of the dbhf results , such as short - range correlations and the structure of isospin 和。介子密度依赖的耦合常数，然后，在不对称系数p 0
The theory is that when a muon encounters a gas molecule , it can knock off an electron , leaving a positively charged ion in its wake 实验原理：当介子遇到气体原子时，将失去一个电子，从而成为一个正离子。
