It is the spin of the quarks and precession of quarks-system caused byspin and electromagnetic-weak forces that keeps the particle world stable.
夸克体系是由自旋着的夸克在电磁－弱相互作用下产生的进动维系稳定的；②物质的质量源于夸克的质量，夸克的质量又源于它的自旋。
According to the relationship between the strong interaction force range and strong coupling constant among quarks in a hadron,a brief computational method on the pocket radius of a hadron is given in this paper .
