✦ Synopsis

The corresponding coagulations are called the when the repulsive Coulomb electrostatic potential of a double primary coagulation and the secondary coagulation. Russel layer is included. A modified stability ratio is presented that takes et al. improved Fuchs' stability theory by considering the into account the effects of both the hydrodynamic interactions and effects of hydrodynamic interactions between the particles the distribution of the thermal energies of Brownian particles.

In addition to that for Brownian coagulation, the stability ratio for calculating the primary and secondary stability ratios. It for the case of weak gravitational/strong Brownian coagulation is obtained.
