摘要：
The study of dust particle charging characteristics under a magneto-plasma has been conducted numerically. The numerical modelling was presented for ion to electron temperature ratio, epsilon=(T(i)/T(e)), from 0.1 to 1, the dimensionless electron gyroradius ratio, beta(e)=R(p)/R(Be), from 0 to 20, and the effective electron, or negative ion, to positive ion mass ratio, aepsilon1/2=(T(i)m(e)/T(e)m(i))1/2, from 2 x 10(-3) to 0.8. The numerical results show that the dust particles charging characteristics are not significantly influenced by the existence of external magnetic field when beta(e) < 1.
