计算结果表明基态能随总角动量的变化曲线只在某些角动量处出现尖角。
We find that the downward cusp of the ground state energy only occurs for several angular momenta.
所以我们把这一哈密顿量变换到瞬时形式下总角动量表象中，并仔细分析所得到的介子径向本征方程的物理内涵。
So we transform it to total angular momentum representation in instant form and explore the physical contents of the meson radial eigen equations.
该哈密顿量所对应的光前形式下的介子本征方程是在螺旋度-动量表象下表述的，不便于得到介子总角动量信息。
The front form meson eigen equations are formulated in momentum-helicity representation which hinders its solution in total angular momentum representation.
