The other way to think about it is divergence is the source rate, it is the amount of fluid that is being inserted into the system, that is being pumped into the system per unit time per unit area.

The seabed erosion - accretion pattern is consistent with the situation of convergence or divergence of sediment transport rate.

Discuss the using of modal interval theory in solving the dynamic eigenvalue of uncertain parameters system. Research the divergence problem of solving interval and convergence rate problem.
