The $\\pi$-$N$ and $\\pi$-$\\pi$ scattering lengths are also calculated for comparison. The calculations are made with heavy quarks corresponding to $m_\\pi/m_\\rho\\approx 0.73-0.95$. The results show that the $N$-$N$ system has an attractive force in both spin-singlet and triplet channels, with their scattering lengths significantly larger than those for the $\\pi$-$N$ and $\\pi$-$\\pi$ cases, a trend which is qualitatively consistent with the experiment.
