I have used a whole month to do this derivation.

![Q_{ijk} = \int_{\mathbf r} \left[ \delta_{ij} ( r^2 - 5 r_i r_j + \frac{10}{3} r_i r_j \delta_{jk} ) r_k - |\epsilon_{ijk}| 10 r_i r_j r_k \right] \rho(\mathbf r) d^3 r](https://s0.wp.com/latex.php?latex=Q_%7Bijk%7D+%3D+%5Cint_%7B%5Cmathbf+r%7D+%5Cleft%5B+%5Cdelta_%7Bij%7D+%28+r%5E2+-+5+r_i+r_j+%2B+%5Cfrac%7B10%7D%7B3%7D+r_i+r_j+%5Cdelta_%7Bjk%7D+%29+r_k+-+%7C%5Cepsilon_%7Bijk%7D%7C+10+r_i+r_j+r_k+%5Cright%5D+%5Crho%28%5Cmathbf+r%29+d%5E3+r&bg=ffffff&fg=333333&s=0 "Q_{ijk} = \int_{\mathbf r} \left[ \delta_{ij} ( r^2 - 5 r_i r_j + \frac{10}{3} r_i r_j \delta_{jk} ) r_k - |\epsilon_{ijk}| 10 r_i r_j r_k \right] \rho(\mathbf r) d^3 r")

But I still do not know whether it is correct or not.
